Prime Minister Rishi Sunak is facing questions about his judgement following the resignation of cabinet minister Sir Gavin Williamson after bullying claims.
Mr Sunak is set to face MPs at Prime Minister’s Questions and is expected to be asked when he learned the full details of the allegations.
Sir Gavin is accused of abusive behaviour towards fellow MPs and civil servants, though denies any wrongdoing.
Labour said the episode has shown “poor judgement and leadership” by Mr Sunak.
Sir Gavin was appointed minister without portfolio after Mr Sunak, a close political ally, won the Tory leadership just two weeks ago.
Complaints against him first emerged when The Sunday Times published a series of expletive-laden texts he sent last month to then-chief whip Wendy Morton.
In the texts, he appears to complain about not having been invited to the Queen’s funeral, and seemingly accuses Ms Morton of “rigging” ticket allocations against MPs not “favoured” by then-prime minister Liz Truss.
He reportedly warned Ms Morton “not to push him about” and said that “there is a price for everything”.
