It’s the end of the road for Boris Johnson, who resigned as Tory party leader on the steps of Downing Street this lunchtime, ushering in the end of a tumultuous and shambolic premiership. The PM finally persuaded himself to quit this morning after a statement of no confidence from Chancellor Nadhim Zahawi and the resignation of Michelle Donelan, education secretary for all of 36 hours. But the coup de grâce was delivered by Sir Graham Brady, head of backbench 1922 Committee, who gave Johnson the latest numbers of MPs who would vote against him in a fresh confidence vote.
