One thing correcting something
mentioned earlier in the thread, the threshold for a vote of no confidence hasn't changed, it's still a simple majority and no confidence
can lead to a dissolution of Parliament still, the 55% refers to a vote for dissolution. Given that dissolution couldn't even be voted on previously this is in no way restrictive of previous freedoms.
The Labour party are promoting the view that they are the same thing, the BBC are happily reporting it, it's not the case.
This explains it better.
