Boris Johnson still has questions to answer over the appointment of Chris Pincher as Conservative deputy chief whip, Labour has said, as a minister said it was possible the prime minister knew of general concerns about the MP’s behaviour.

Johnson faces a backlash for promoting Pincher despite what staffers say were warnings about sexual misconduct by him.
