The Labour Party has accused Boris Johnson of a “prime ministerial cover-up” over bullying allegations against Priti Patel, and his refusal to sack the Home Secretary.
On Thursday evening, details of the long-awaited report emerged suggesting she had broken the ministerial code.
It is thought she will issue an apology after sources suggested on Thursday any bullying was “unintentional”, but that she will remain in her post.
Shadow home secretary Nick Thomas-Symonds told BBC Radio 4’s Today programme the report into her behaviour should be published “in full, line by line” and both Ms Patel and the Prime Minister should answer questions in the Commons: “Because the revelation in recent days have been extraordinarily serious.”
He added: “I’m afraid this really does have all the hallmarks of a Prime Ministerial cover-up and raises questions about his judgment.
“If what has been reported is correct, then it is tantamount to the Prime Minister condoning bullying.”
Ministers and backbenchers have rallied around Ms Patel, calling the Home Secretary “kind and courteous”.
Health Secretary Matt Hancock on Friday morning said: “In my extensive dealing with Priti Patel she has been nothing but courteous and kind, and she is working hard to deliver the commitments on which we were elected.”
On Thursday evening, Minister for Middle East and North Africa at the Foreign, Commonwealth and Development Office, James Cleverly told Question Time: “She has always expected and demanded that people work hard and I think that that is a completely legitimate attitude to take into Government”.
Foreign Affairs Committee chairman Tom Tugendhat said Ms Patel was: “hard working, determined and has been very kind to many”.
Liaison Committee chair Sir Bernard Jenkin added: “Priti may have lessons to learn, but so have some far better-educated officials who should know better.”
However the boss of the FDA union for civil servants Dave Penman said she must go, referencing the ministerial code’s zero tolerance policy on bullying.
He told BBC’s Newsnight programme it appeared as though the Prime Minister had decided that “bullying is OK as long as it’s in a limited and specific way.”
The Home Secretary was accused of bullying her department’s most senior civil servant Sir Philip Rutnam in February, shortly before he resigned.
Sir Philip accused Ms Patel of spearheading a “vicious and orchestrated briefing campaign” against him, and that he had received allegations of Ms Patel “shouting and swearing, belittling people” and “making unreasonable and repeated demands”.
In April, he formally launched legal action against the Government claiming “constructive dismissal”.
