What's the point of playing safe. In politics, sometimes you have to take a risk. Especially if you are leader of a third party.
The news channels are reporting that Clegg and Cameron had a one on one meeting tonight, lasting for over an hour at Admiralty House. It was described as "constructive and amicable".
The fact is that both party leaders are taking risks, which if things go wrong, will be very damaging to them personally. Good on them for having the courage to dare.
