Boris Johnson is calling on MPs to back his plan to hold an early general election on 15 October. The PM has laid a motion in the Commons to secure the poll. To succeed, it needs the support of two-thirds of MPs. But Labour, the SNP and the Liberal Democrats have said they will not vote in favour. It comes after MPs backed a bill to block a no-deal Brexit if the PM hasn't agreed a plan with the EU ahead of the 31 October deadline.
