When Rishi Sunak stunned his cabinet colleagues by calling a snap election, they feared the worst. Fast forward a month and what they originally saw as the worst-case scenario now looks like quite a good result. At the time, losing the election but retaining 200 MPs seemed plausible. While the polls vary, the consistent theme now is that the Conservatives are on course for their worst defeat in history – and could end up with as few as 50 MPs.
