The past couple of weeks have seen several Liberal Democrat councillors switch allegiance to the SNP, no doubt partly due to disappointment with the actions of their former party at Westminster and partly with half an eye on next year’s local elections. In a UK context, they are not alone.

The Lib Dems difficult position is not getting any easier for Nick Clegg; his call for a more ‘muscular liberalism’ and objections outwith the coalition agreement won’t be accepted by the Conservatives and it also undermines his party’s stance on saying they had to increase tuition fees and increase VAT because it was in the coalition agreement. Why did Nick Clegg accept those policies but is now reacting against the NHS proposals when all of those policies were in the agreement? I suspect that will be the next circle the Lib Dems will have to square in the next few weeks, aside from dealing with Chris Huhne’s exit from Government of course.

The next Westminster election is probably still some way off, if the coalition does hold for the full five years then we have four long years to go. However, if any MPs are thinking about switching allegiance for principled or pragmatic reasons (particularly in Scotland in light of the Holyrood results), they are probably best to do so in the next year or two in order to avoid too many charges of naked opportunism, not to mention time to let local activists warm to them.

So which Scottish MPs might be considering the move?

Mike Crockart – Edinburgh West
Won a narrow selection contest to take the supposedly safe Lib Dem seat in 2010 but has since quit Government to vote against coalition proposals on tuition fees and watched on as the Lib Dems were wiped out in the Lothians in the Holyrood elections. A repeat result in next year’s council elections may well focus the mind for this young, up and coming politician.
Likelihood of defection? Medium

Alan Reid – Argyll & Bute
In the past three Holyrood elections in this area, the Lib Dems have slumped from 1st (35% voteshare) through 2nd (32% voteshare) to 4th (12% voteshare). One coudl argue that the writing must surely be on the wall for Alan Reid even at this early stage.
Alan voted against the proposals to increase university tuition fees so is clearly not afraid to stand up to and against the party machine.
Likelihood of defection? Medium

Michael Moore – Tweedale, Ettrick & Lauderdale
Michael is the current Secretary State for Scotland but his distaste for the coalition was made known via a secret recording of comments regarding the tuition fees vote. Apparently “Tuition fees … [are] the biggest, ugliest, most horrific thing in all of this” so there is scope for further discord and not respecting party decisions. There is also currently a whispering campaign against Michael as a result of his intransigence in moving towards a more federal UK, which is Lib Dem policy.
Michael holds only a 1,489 majority over Labour from 2010.
Likelihood of defection? Medium

Sir Robert Smith – West Aberdeenshire & Kincardine
Robert holds a 3,684 majority over the Conservatives in that rarest of constituencies in Scotland, a Tory/Lib Dem two horse race. I don’t know if the MP is an orange-booker or sympathetic to the blues but Robert’s grandfather served this constituency as a Tory and he is a ‘3rd baronet’ which, I don’t know what it means, but it sounds more Tory than Lib Dem to me.
Swinging allegiance just before 2015 from orange to blue would virtually cement re-election, if the local Tory group allowed it of course.
Likelihood of defection? Medium

Jo Swinson
Jo fought off a strong challenge from Labour in 2010 to hold onto her East Dunbartonshire constituency by 2,184 votes. The Conservatives and SNP were a distant 3rd and 4th. Despite the SNP taking near-equivalent Strathkelvin and Bearsden in 2011 from Labour’s David Whitton, this should be a Labour/Lib Deb two-horse race in 2015.
It is early days but given that the Lib Dems slumped to 4th place in 2011 with only 7.7% of the vote, one has to assume that the writing is already on the wall for Jo Swinson’s tenure as an MP. Crossing the floor to Labour is probably the Scottish Liberal Democrats’ Deputy Leader’s best chance of re-election.
Likelihood of defection? Low

Menzies Campbell/Charlie Kennedy/Malcolm Bruce
Rightly or wrongly, I view this trio as a mini-group of MPs within MPs. Similar political views and similar length of experience, they have invested much of their career to the benefit of the Lib Dems but these senior politicians are conspicuous by the their silence and, if one was to take drastic action, one has to assume all three of them would together. The age and stage of their careers probably means they’ll ride out this chapter of the Liberal Democrat story without objecting too radically.
Likelihood of defection? Low

John Thurso – Caithness, Sutherland and Easter Ross
Probably enjoys a strong enough personal vote to be too overly-concerned with not winning at elections any more. May also be considering retirement in 2015 having served three parliamentary terms since 2001.
Likelihood of defection? Low

Alistair Carmichael – Orkney & Shetlands
The islands have been Lib Dem held since the 1950s and Alistair was President of the Liberal Club way back when he was a student.
Likelihood of defection? Non-existent

Danny Alexander – Inverness, Nairn, Badenoch & Strathspey
Danny holds a 8,765 majority over Labour from the 2010 election which is a winnable margin looking ahead to 2015, even with the Chief Secretary to the Treasury being the poster boy for the Lib Dems, and flak jacket for the Tories, when it comes to cuts. Danny seems to embody the rural, pragmatic, intellectual wing(s) of the Liberal Democrats and it is difficult to picture the man with any other rosette on his lapel.
Likelihood of defection? Non-existent
