Go to the country?

It has been suggested that, if Jeremy Corbyn wins the forthcoming Labour leadership contest, the Prime Minister should immediately call a snap general election which, conventional wisdom has it, the Tories would win by a landslide.  Well, would they - and more to the point - could they?  The days when the Prime Minister could call a general election whenever they liked - and for the most part would do so at the most favourable moment for themselves - have gone with the passing of the Fixed-term Parliament Act of 2011, and now the next general election is set for 7th May 2020.  Unless, that is, at least 434 MPs (two-thirds) vote to have an earlier one.  Given that turkeys do not vote for Christmas, and that the Government have only a small majority, this is highly unlikely.  Equally unlikely is that the Commons pass a vote of no confidence in the government.  So, much though she might like the idea, a snap election is not on.
