Because his party has never been able to gain electoral traction, we were told on Sunday by The Guardian/Observer:

Nick Clegg, the Liberal Democrat leader, today called for the creation of a constitutional convention to bring about wholesale reform of the way Britain is governed.

Isn’t that just like a Liberal/liberal? :-) Because he has been unable personally to get ahead (in this case, meaning win some more seats), he thinks the solution is to change the rules to suit himself.

In a speech to his party conference, he stressed that he would only form an administration with another party committed to “a new type of government … based on pluralism instead of one-party rule”.

…”Will I ever join a Conservative government? No. Will I ever join a Labour government? No

And will Mr Clegg ever form his own Liberal Democratic government? Uh, no.
