Can you imagine the attack that Labour would have faced if it had tried to introduce this new rule to prevent dissolution of parliament without the support of 55% of the House?
This raises the spectre of a government losing a finance bill or other confidence motion or even being entirely unable to push legislation through the House, but being able to cling on to an illusion of government.
If it was applied to an MP or a councillor, they would be overjoyed at being secured against all but an overwhelming defeat. This is actually an abuse of the constitution for a shamelessly party political motive on the part of the Liberal Democrats, as they want to prevent the Tories from choosing the right moment to abandon the coalition, drop their mates and run to the polls.
It is wrong and should not be allowed to pass. There already seems to be a groundswell of opposition on the government back benches, so I'm going to put my faith in the Tory traditionalists actually doing the right thing and stopping this legislation before it gets going. I doubt Cameron wants it, which is why he's made sure that Clegg gets to front this up to the House when it reconvenes next week.
