Based on Ladbrokes’ odds in each individual constituency, we’re projecting that five seats in Scotland will change hands at the next general election. Amazingly, not a single seat switched in 2010 (ignoring a couple of seats regained after by-elections). Here are the constituencies most at risk this time. The “lose chance” is the probability, based on our odds, of the incumbent party being defeated :

Danny Alexander is given a 57% chance of losing his Inverness seat, but we aren’t forecasting a gain for any party, because the SNP and Labour are both in with a reasonable chance of winning it.  So, that still remains in the LD column in our overall totals below as he is still just about favourite, although odds-against.

We have the SNP as gaining two seats from the Liberal Democrats, but both are very hard to call, especially Argyll & Bute where they actually came fourth last time. This is probably the most difficult seat in Britain to forecast, with all four parties in with a shout. Their best chance of any gains from Labour come in Ochil & Perthshire South and Falkirk – you can back them at 7/4 in each of those two seats.

The Tories are forecast to remain with just one Scottish MP, although they have a couple of very plausible targets in Berwickshire, Roxburgh & Selkirk at 11/10, and Aberdeenshire West & Kincardine at 6/4.

Here are the projected new seat totals for Scotland, (with changes from 2010):

  • Lab 43 (+2)
  • SNP 8 (+2)
  • LD 7  (-4)
  • Cons 1 (nc)

Clearly, the big unknown is how the result of the Independence Referendum will affect voter behavior. If there is a YES vote, then these MPs will presumably be out of a job within two years of the election.
