Boris Johnson's ethics advisor dramatically quit tonight, weeks after clashing with the PM over his Partygate behaviour.
In a move that could derail the Prime Minister’s bid to reset his premiership, the usually wordy peer released a terse, 21-word statement simply saying it was “right” for him to quit.
It puts Mr Johnson in fresh danger, with two by-elections looming next week - and the Privileges Committee's investigation into whether he lied about Downing Street parties.
