John Bercow was under intense pressure last night after Theresa May demanded an investigation into claims he bullied an aide.
The Commons Speaker faced a call to quit after his former private secretary accused him of foul-mouthed tirades and attempts at physical intimidation.
Angus Sinclair said he was forced into early retirement with an £86,250 pay-off on condition he did not make any complaints. Mr Bercow has strenuously denied the claims.
But yesterday Downing Street said there should be a ‘proper investigation’ – and twisted the knife by outlining three ways in which this could be carried out.
Mrs May’s official spokesman suggested an existing inquiry into Commons bullying should have its remit widened to allow it to look at individual cases such as allegations against the Speaker.
