The Lib Dems promise to back the ’largest’ party – but do they mean votes or seats?

It’s entirely possible that Labour could end up with the most seats but a smaller share of the vote than the Tories.

So then, how do we, under the crazy first-past-the-post electoral system that we’re lumbered with, define the word ‘largest’.

I only ask, because, as Labour’s opinion poll ratings start to shrink and suddenly they start thinking that perhaps, this time, it would be best to do a bit of planning for how a coalition agreement might be hammered out, rather than trying to sort it on the fly (prompted by the publication of Andrew Adonis’s new book on the chaos that occurred last time), it suddenly seems a very relevant question.
