Fixed-term Parliaments Bill

I am fascinated by the hon. Gentleman's logic, but does he accept that, with the exception of the Parliament between 1987 and 1992, every Parliament since the 1950s that has lasted longer than four years has ended with the defeat of the governing party at a general election? Frankly, if the Prime Ministers in those Parliaments could have gone on longer they would have done, just to avoid the electorate.
