An interview with Clegg, and a commentary piece on it. Note the headline chosen for the interview:
Nick Clegg: ‘You can’t have Gordon Brown squatting in No 10 because of this clapped-out old system’...
“It’s not for me to be kingmaker. There are 45m kingmakers out there — the voters. I will talk to whoever the electorate says is clearly in play. In the event that a party has more votes and more seats, but not a majority, it would be wrong not to acknowledge up front that that party has the right to seek to govern. I tie my hands in that sense,” he says.
This is the line he will desperately try to hold until polling day — making it sound like voters will have the final say in what he’s started calling, a bit cheesily, “a people’s election”. The problem, as he knows full well, is that a hung parliament is unlikely to produce a party with both the most seats and the largest share of the vote.
Because of the vagaries of the system, Labour could get fewer votes than the other two parties, but still have most seats. If that happens, Clegg will have the casting vote.
So I push, and push, and finally he helps a bit, by declaring that if Labour gets the smallest share of the vote of the three main parties and the most seats, he would not tolerate Brown remaining prime minister.

Nick Clegg: I will not prop up 'irrelevant' BrownNote the writer of the first piece is not really accurate, when they say "a hung parliament is unlikely to produce a party with both the most seats and the largest share of the vote". In fact, the most likely outcome at the moment looks like the Tories getting the largest share of the vote and the largest number of seats - but not an overall majority (and an overall majority would make Clegg's thoughts irrelevant anyway). But one thing from this does seem to be a fairly definite ruling out of a formal coalition with Gordon Brown, if Labour come third in the share of the vote.
And while he's personalised it by talking about Brown, I'd say there's no decent case to be made for a coalition with Labour just as long as they drop Brown and make someone else leader.
