For why I think the majority will be less than expected - it's not because I think the Tories will do well. I think they're absolutely tanked. However I think there will be a higher-than -expected "protest vote" for non-Labour/Tory candidates and that will upset the apple cart a bit.

I have absolutely NO idea what's going to happen in terms of Scottish seats. Bizarrely t this point my "ideal" for Scotland would be a tonne of SNP MPs in Westminster, but PR in Holyrood with a fairly even split between multiple parties.
