A minor correction has been made to the boundary between Thornaby and Middlesbrough (near to Middlesbrough town centre) that was in existence between 1974 and 1983. In Area Map & Table 76b this has slightly changed sub-Areas 13, 14, 16 & 17, but has no other knock-on consequences.

A continuing trawl of the @natlibscot.bsky.social maps collection has necessitated another correction to the parlconst website. The focus has been on divided non-Metropolitan towns and cities, for which large scale boundary maps were hard to come by when the parlconst website was first created.

Makerfield is the third constituency to be having a by-election on 18th June. Makerfield was created as constituency in 1983. The biggest part of the new seat came from the former Ince constituency. That said, the town of Ince was only in Makerfield constituency between 1997 and 2010.

The will be a by-election in Arbroath & Broughty Ferry on 18th June. This constituency came into existence for the first time at the 2024 General Election, gaining the majority of its electorate from the previous Dundee East seat, with the remainder coming from Angus.

One of my eagle-eyed regular correspondents has spotted that a detached part of Hallamshire constituency, to the south-east of Sheffield including Handsworth and Woodhouse, that existed from 1885 to 1918, was not being shown on the Constituency Maps for Northern England. This has now been corrected.

There will be three parliamentary by-elections on 18th June. One will be in Aberdeen South. It, and Aberdeen North, has existed continuously since 1885. The only other examples of Divisions of Boroughs/Burghs to have done so are Islington N, Bristol S, Liverpool Walton, Edinburgh S & Edinburgh W.

Sometimes you just come across something that makes you wonder how you never knew about it. Today's discovery is that Alexander Kerensky, leader of the Russian provisional government following the February revolution in 1917, did not die until 1970 and is buried in Putney Vale cemetery.

I've tried this a couple of times - but I've only just noticed that it is not based on current constituencies, but those that were in existence from 2010 to 2024.

There was an underestimate of the proportion of Great Grimsby & Cleethorpes that came from Cleethorpes in 2024. Correcting this has changed the size of all the sub-Areas in the current constituency. As a result, some of the lines on the Humberside (South) Constituency Chart have changed thickness.

There is an ongoing search for corrections to the parlconst website. Most are minor & are reported on the website's changelog. The latest has been an arithmetic error that caused an underestimate of the size of sub-Areas 5 & 6 in Oxfordshire, representing the transfer from Witney to Banbury in 2024.

The order of names on ballot papers matters. The LB of Redbridge has 22 wards (19x3 and 3x2 councillors). 11 of the 22 wards returned more than one party (in one case a three way split). Therefore for 23 party ward listings, only some were elected. In 18 of these it was those alphabetically first.

My ward is electing two councillors today. I always vote, but I don't know what to do today. There are 10 candidates (five parties standing). The only two parties from which I've received communication I will not vote for. But, even online, I can't find any information about the other candidates.

The Constituency Chart for Barnet, Enfield and Haringey has been corrected to show the transfer in 1918 from Hornsey to Stoke Newington.

In the boundary review implemented in 2024 a new cross-county constituency of Hitchin was created. This was formed of parts of the former Hitchin & Harpenden (in Hertfordshire) and parts of Bedfordshire NE and Bedfordshire Mid. www.parlconst.org/new-constitu...

As Finchley constituency was unchanged in 1945, it should have have a red line on the Constituency Chart joining it to its 1918 predecessor, not a thick black line as shown previously.

A continuing trawl through @natlibscot.bsky.social recently out of copyright maps has thrown up another correction needed on the @parlconst.bsky.social website for the constituency boundaries in operation from 1974 to 1983. This time it affects Plymouth.

As they come out of copyright after 50 years, the @natlibscot.bsky.social has been making more maps available on-line. In particular, the county administrative area maps from the early 1970s which show the Boundary Commission proposals from the Second Periodic Review that were implemented in 1974.

Today the Irish National Archives has made available the records from the first census conducted by the Irish Free State in 1926, now that it is its 100th anniversary. I've already spent several hours down this fascinating rabbit hole. nationalarchives.ie

I've had a few queries recently via the website which could be answered easily by looking at the web page for the the relevant constituency group. It appears that new users of the site had not been finding the constituency group pages. I've now changed the wording on the homepage to make it clearer.

I once nearly got arrested for trying to break out of a house.

I never knew either of them. One was a miner in the Nottinghamshire coalfield, who fought as soldier in WWI, fighting at Gallipoli and on the western front (where he was gassed). The other was a gas works manager at Youghal, Ireland.

Despite not previously being included in the name, Denton was in Manchester Gorton constituency between 1955 and 1983 and it was part of Gorton constituency between 1885 and 1918.

The Gorton & Denton by-election will be held on 26th February. The constituency was created in 2024 from parts of the former Manchester Gorton, Manchester Withington and Denton & Reddish seats. The parts coming from the first two are in the City of Manchester, while the rest are in Tameside MB.

Belatedly I have got round to listening to the first of this pair of episodes. Excellent analysis by @robertsaunders.bsky.social if you want to understand the first two General Elections covered by the parlconst website. Well worth subscribing to @ppfideas.bsky.social just to get the second episode.

The longest wait since a General Election for the definitive account (by @robfordmancs.bsky.social @timbale.bsky.social @drjennings.bsky.social @psurridge.bsky.social) to come out, but it has finally arrived to add to the series since 1945. That said, it also has the biggest number of pages of any.

Last night's event to mark the forthcoming publication of the definitive account of the 2024 General Election, with two of the authors: @timbale.bsky.social & @psurridge.bsky.social Hopefully one can get one's hands on the actual book by Christmas.

10 factorial (10! = 10x9x8x7x6x5x4x3x2x1) is the exact number of seconds in six weeks.

Croydon West (1950-55) had been wrongly labelled as Croydon South on the constituency map for Southern England. This has now been corrected. www.parlconst.org/constituency-maps/england/1950

Bessie Braddock's statue at Liverpool Lime Street station. What you can't see from this picture is that she appears to be in conversation with Ken Dodd.

Been doing some tidying. Very pleased that I now have my collection of Boundary Commission reports arranged in chronological order. From the 1868 report for England & Wales through to the Fifth Periodical Report for Northern Ireland (2008), as well as some interim & local government reviews.

My guess was correct - the Bayeux Tapestry will be displayed in the British Museum next year. I very much doubt that if I go and see it there that I will be the only visitor, as I was in Bayeux in 2021 in the brief period that year when travel to France was allowed.

No inside knowledge, but ... President Macron arrives in the UK tomorrow for a 3-day state visit. There appears to be a gap in his itinerary on Wednesday afternoon. Very unusually the British museum is shut for the day on Wednesday. My guess is he will he will announce a loan of the Bayeux Tapestry.

Have just finished listening to this excellent 20 part series on the 1945 General Election and its consequences, by David Runciman. If you are interested in electoral history, I thoroughly recommend it. With some insightful contributions on the political aspects from @robertsaunders.bsky.social

The boundary between the West and East Divisions of Southend between 1955 and 2010 was a block further to the east in the vicinity of Roots Hall (Southend United's ground) than previously shown. This has had a small effect on the size of sub-Areas 27 & 28. www.parlconst.org/new-constitu...

In addition to the correction made recently, the 1917 Boundary Commission recommendations were not fully implemented for Forest of Dean, Gloucester and Stroud. Also, from 1918 to 1950 the area occupied by the County Mental Asylum was an exclave of Stroud constituency wholly within Gloucester.

Over the past few months the website has been regularly updated with corrections identified by a number of correspondents. I am pleased to say that the backlog of these has finally been cleared. I am sure there will be more in the future and all are listed on the website's changelog.

Catching up on some podcast listening. This episode explores whether the UN small area population estimates undercount rural areas. This data is used, although calibrated by the size of know transfers between constituencies, in the parlconst model to derive the size of historic transfers.

I don't usually post personal stuff from this account, but I thought I would share a salutary lesson for anyone who uses Microsoft Outlook for their email. A thread: ... (1/6)

A new sub-Area 18 has been added to Area Map & Table 63a to reflect that the Wilderspool area of Warrington was in Knutsford constituency from 1885 to 1918. www.parlconst.org/new-constituency-groups/north-west/63-cheshire

The parish of Seaborough was in South Somerset from 1885 to 1918 before transferring to the West Dorset constituency, where it has remained ever since. Correcting this has created a new sub-Area 17 in the Dorset Area Map & Table. www.parlconst.org/new-constituency-groups/south-west/52-dorset

The Rode Hill area of the village of Rode (formerly Road) was in Wiltshire until 1937 and Westbury constituency until 1950. Showing this correctly has created a new sub-Area 12 in Area Map & Table 49b. www.parlconst.org/new-constituency-groups/south-west/49-somerset

A number of corrections have been made to boundaries in Gloucestershire. The most significant error was previously showing the 1918-1950 boundaries as recommended by the 1917 Boundary Commission, whereas the actual implementation had Tetbury RD in Cirencester & Tewkesbury and not in Stroud.

Between 1885 and 1918 the far north-western part of Malvern was in Herefordshire (Leominster constituency). This is now reflected in a new sub-Area 9 in Area Map & Table 45b. parlconst.org/new-constituency-groups/west-midlands/45-herefordshire-and-worcestershire

A northern part of Newport in Shropshire had been in Staffordshire until the 1960s (and in Stafford & Stone constituency until 1974). Correcting this has created a new sub-Area 6 in the Shropshire Area Map & Table. www.parlconst.org/new-constituency-groups/west-midlands/44-shropshire

Upper Ipsley was created as a parish in 1894, being the part of Ipsley which joined Redditch UD. However it remained part of Warwickshire for parliamentary purposes until 1918. This was previously wrong on the website, but now remedied with a new sub-Area 20 in Area Map & Table 45c.

The boundary maps on the @parlconst.bsky.social website were largely created by working backwards in time and noting changes. Problems sometimes arise when the constituent parts of constituency don't change in a review, but the boundaries of one or more of those parts has changed slightly. (1/4)

A new sub-Area 9 has been added to Area Map & Table 38d - Birmingham (South) to reflect the current couple of streets that would have been in Birmingham S constituency from 1885 - 1918 (not Worcestershire E) and then transferred to Birmingham Moseley in 1918. www.parlconst.org/new-constitu...

There were an awful lot of very minor changes to county boundaries in the early 1990s. Have just finished three days solid work trying to make sure that Derbyshire's pre-1997 boundaries are shown correctly on the parlconst.org website. (1/2)

A question for those who download boundary datasets from the website. Because of the way uMap (which hosts the zoomable maps) used to position the showing of the constituency name, the website maps (in England only) treat each detached part of a constituency as a separate feature. (1/4)

Multiple minor corrections have been made to the website maps showing the boundary between Nottinghamshire and Yorkshire before 1997, mainly relating to the boundary of Bassetlaw constituency. In most cases these changes are too small to be reflected in the in the Area Maps & Tables.
