Top of that list are the SNP leader at Westminster, Ian Blackford (Ross, Skye and Lochaber) and his neighbour Drew Hendry (Inverness, Nairn, Badenoch and Strathspey). Their seats would effectively be merged into a single, huge constituency, Highland Central.
A similar fight could play out between Tory MPs Andrew Bowie (West Aberdeenshire and Kincardine) and Colin Clark (Gordon) over the new constituency of Gordon and Deeside.
Boundaries would change for all Glasgow MPs, but Patrick Grady (Glasgow North) could face the biggest challenge in finding a new seat, as would Marion Fellows, whose Motherwell and Wishaw constituency faces being carved up.
In south Ayrshire, the SNP’s Philippa Whitford and Bill Grant could end up facing off against each other for the new Ayr and Carrick seat, while in Edinburgh, Labour’s Ian Murray and the SNP’s Joanna Cherry face significant changes to their electorates.
