UK party leaders making firm promises about coalition arrangements (or rejected arrangements) that they mathematically can’t possibly keep are one way voters lose all trust in their public officials. I get that they’re trying to discourage splinter/protest voting by taking a hard line without wiggle room before the election, but the math just isn’t there to be saying stuff like this, and at a certain point it’s just pure misrepresentation of reality.
Labour and Liberal Democrat leaders in the past couple weeks have been painting themselves into a corner on coalition promises, wherein they’ll either force a 2nd election or have to dynamite the corner to escape the foolish pre-election promises.
If the Labour Party will not make any kind of deal with the SNP (which is their latest position) and the Conservatives and Liberal Democrats won’t either, how exactly is anyone supposed to form a government? Excluding the fairly astronomically unlikely possibility of a Conservative-Labour grand coalition, no two parties (or even three!) will have enough seats for a majority without involving the SNP. Everyone will be 20-50 seats short.
Are you going to throw this over to Northern Ireland to pick the PM? (Is that really better than letting Scotland do it?) Are you going to force new elections? What’s the realistic game-plan here?
