Ed Miliband says PM is 'a stain on our politics'
Labour's Ed Miliband has said that the prime minister has become "a stain on our politics" but lacked the "scruples" to resign.
The shadow climate change secretary also called on Boris Johnson to resign and said it was up to the Conservative Party to listen to those who have resigned and act.
This comes after four senior aides to Boris Johnson resigned from Downing Street within hours of each other amid growing pressure on the prime minister.
