How might Scotland's electoral map be changing? How might Scotland's electoral map be changing?
(30 days later)
Big changes are proposed for Glasgow - existing boundaries are the black lines, with colours showing new proposals The new boundaries will see thousands of voters move into new constituencies
Plans for sweeping changes to Scotland's electoral map are being finalised, as part of a review which will see the country have two fewer MPs.Plans for sweeping changes to Scotland's electoral map are being finalised, as part of a review which will see the country have two fewer MPs.
The Boundary Commission for Scotland has put its plans out for a final public consultation before they are sent for approval in 2023. The Boundary Commission for Scotland has submitted its final recommendations to the Westminster parliament, and they are likely to be in place for the next general election.

The idea is that MPs should each have roughly the same number of voters in their patch, so that representation is balanced fairly across the country.The idea is that MPs should each have roughly the same number of voters in their patch, so that representation is balanced fairly across the country.

MPs chiefly represent people rather than places - but changes can prove controversial given the importance people and indeed politicians invest in their places, particularly if changes cut across historic communities.

This is why there have now been three rounds of consultation as the current proposals are refined - and the latest and final of which runs until 4 December. There were three rounds of consultation while the current proposals were refined, with amendments - sometimes quite big ones - made in light of the comments submitted at each stage.

We have known since January 2021 that the latest shake-up will change the number of MPs from each of the nations of the UK, on account of population changes - because it has grown more quickly in some areas than in others.We have known since January 2021 that the latest shake-up will change the number of MPs from each of the nations of the UK, on account of population changes - because it has grown more quickly in some areas than in others.
There is now a greater share of voters located in South East England in particular than there was when the current set of boundaries were drawn up - so to keep within the quotas, those people need an extra seven MPs.There is now a greater share of voters located in South East England in particular than there was when the current set of boundaries were drawn up - so to keep within the quotas, those people need an extra seven MPs.
The new boundaries will see England gain 10 seats overall - although some regions like the North East and North West will have fewer than previously - while Scotland will have two fewer, and Wales will lose eight.The new boundaries will see England gain 10 seats overall - although some regions like the North East and North West will have fewer than previously - while Scotland will have two fewer, and Wales will lose eight.
There will likely be a political impact from this, because of the traditional power bases of the different parties located in different parts of the country.There will likely be a political impact from this, because of the traditional power bases of the different parties located in different parts of the country.
The Conservatives would hope to do well from increased representation in South East England, while Labour could lose out if there are fewer seats in the northern areas of England, and Plaid Cymru are particularly unhappy about the drop in seats in Wales.The Conservatives would hope to do well from increased representation in South East England, while Labour could lose out if there are fewer seats in the northern areas of England, and Plaid Cymru are particularly unhappy about the drop in seats in Wales.

Where might the biggest changes be seen?Where might the biggest changes be seen?
Aberdeenshire and Moray could see some big changes to the electoral map - existing seats outlined in black, new ones in colour The changes proposed in the west of the central belt - with council areas outlined in red, and new constituencies in black
One of the disappearing seats is coming from Glasgow and the surrounding area, while the other is coming from the north of the country, between Aberdeenshire and the Highlands.One of the disappearing seats is coming from Glasgow and the surrounding area, while the other is coming from the north of the country, between Aberdeenshire and the Highlands.
The old Moray constituency is to be cut in two, with Elgin joining a new Nairn, Strathspey and Moray West seat which spreads south down the A9 to Dalwhinnie. The former is probably the easiest to explain, with the current Glasgow Central constituency essentially being broken up and parcelled off into the city constituencies around it.
On the other side, Keith and Buckie would move over into Aberdeenshire North and Moray East - a very coastal grouping which includes Peterhead and Fraserburgh. There are changes across the region though, which will go from ten MPs in total down to nine.
The inland parts of the old Banff and Buchan constituency are to join up with the old Gordon one to create Aberdeenshire Central. Inverclyde is to inherit the western chunk of Renfrewshire, while the old East Dunbartonshire seat expands north to become Mid Dunbartonshire.
Meanwhile, the current Glasgow Central constituency will essentially be broken up and parcelled off into the city constituencies around it. On the other side of the city, a new Motherwell, Wishaw and Carluke seat is to spread out to the east, while Lanark will be split off to join Hamilton in a new constituency called Hamilton and Clyde Valley.
Inverclyde is to inherit the western chunk of Renfrewshire, while the old East Dunbartonshire seat would expand north to become Bearsden and Campsie Fells. Big changes are planned in the north of Scotland - new constituencies are in black, council areas in red
On the other side of the city, a new Motherwell and Clydesdale North seat is to spread out to the east, while Lanark will be split off to join Hamilton in a new constituency called Hamilton and Clyde Valley. The old Moray constituency is to be cut in two, with Elgin joining a new Moray West, Nairn and Strathspey seat which spreads south down the A9 to Dalwhinnie.
The remains of the Inverness, Nairn, Badenoch and Strathspey seat is then extended right across to the coast, becoming Inverness, Skye and West Ross-shire.
The commission faced particular challenges in dealing with vast, sparsely-populated areas in the Highlands, but the tinkering with this area expanded right across to the east coast - the region as a whole going from having eight seats to seven.
The splitting of Moray will see Keith and Buckie move over into Aberdeenshire North and Moray East - a very coastal grouping which includes Peterhead and Fraserburgh.
The inland parts of the old Banff and Buchan constituency are to join up with the old Gordon one to create - no prizes for guessing - Gordon and Buchan.
If this is all getting a bit dizzying, maps of all the proposals can be found on the Boundary Commission website.
What else is changing?What else is changing?
Orkney and Shetland and Na h-Eileanan an Iar are protected in law, and a handful of other seats are being retained in their present shape or only having a change of name.Orkney and Shetland and Na h-Eileanan an Iar are protected in law, and a handful of other seats are being retained in their present shape or only having a change of name.
But, otherwise, there are big changes right across the country - even beyond where seats have "disappeared".But, otherwise, there are big changes right across the country - even beyond where seats have "disappeared".
A fresh attempt has been made at carving up the sparsely-populated Highlands into manageable chunks, with Caithness, Sutherland and Easter Ross expanding to take in Dingwall. Clackmannanshire has ceded Dollar to Dunfermline, with a new Alloa and Grangemouth seat spreading south across the Forth - but without including any bridges, meaning the local MP will need to nip into a neighbouring constituency to traverse their patch. Or buy a boat.
The old Inverness, Nairn, Badenoch and Strathspey seat is being split between the new Nairn, Strathspey and Moray West constituency mentioned earlier, and a new Inverness-shire and Wester Ross seat which covers much - but not all - of the old Ross, Skye and Lochaber. Broughty Ferry - which has long considered itself somewhat independent from Dundee - has been split off into a seat with Abroath, taking the Whitfield and Douglas areas of the city with it.
The southernmost chunk of that old seat is off to join Arygll, Bute and South Lochaber. If you're increasingly lost at this point, there are detailed maps on the Boundary Commission website. That leaves the remains of the city as Dundee Central, no longer split into east and west, while the leftover parts of the old Angus area will absorb most of the old Perth and North Perthshire patch to become Angus and Perthshire Glens.
The review can create some oddly-shaped seats - such as the move to take Denny out of Falkirk and into Clackmannanshire and Forth Valley Meanwhile in the capital, East Edinburgh will expand to capture much of Musselburgh from East Lothian - a move which has seen the latter constituency renamed "Lothian East".
The previously over-mighty Falkirk seat will lose Denny to a new Clackmannanshire and Forth Valley constituency - which some locals have already spotted spans two sides of the Forth without including a bridge, meaning the local MP will need to nip into a neighbouring constituency to access half of their patch. Or buy a boat. This has raised some eyebrows with locals, but the commissioners say it was necessary because the seat no longer shares the boundaries of the local council - so the name has to change to avoid confusion.
A big chunk of Angus is to join a new Dundee East and Arbroath seat - which essentially starts from Broughty Ferry - while the bulk of the city remains in Dundee West.
Further down the Tay, there is to be a new seat of Perth and Loch Leven. It takes in a big chunk of the old Ochil and South Perthshire seat, although Dollar has been split off to join Dunfermline and East Ochils and Auchterarder is part of a new Clackmannanshire and Forth Valley seat.
Meanwhile in the capital, East Edinburgh will expand to capture Musselburgh from East Lothian, while losing some of its western fringe to Edinburgh South.

The current set of proposals is due to be submitted to the Speaker of the House of Commons for approval in July 2023. The current set of proposals has made it to the Commons, and the UK government has four months to submit an order to the Privy Council to turn them into a reality.
It is not clear what would happen if there was an early general election or a change of government in the interim, because election returning officers are going to need some time to get to grips with the new set-up. Ministers are not allowed to change any of the recommendations without the approval of the Commissioners.
For now it's down to the public to have a final say on the proposals, to see if any changes are made before the last consultation closes. Once the Privy Council approves the order, the new constituencies take effect at the next election.
So unless there is a big change or a snap election over the next couple of months, it looks likely these changes will go ahead.
