Sunak surges and Starmer slips
Quite what is driving the betting is hard to say but Chancellor Sunak has moved sharply and as I write (2100 BST) is only 1% behind the LAB leader.
Of course everything in this market depends on whether there is a change of Prime Minister before the general election or afterwards. For it is hard to see Sir Keir Starmer getting the job without securing enough MPs – and the only development that can do that is a general election.
Sunak has by far the best leader ratings of any current UK politician and has been the driver of the popular half price meals plan which has come to an end today. He appears well set to take over at Number 10 should should Johnson decide to go or is forced out.
