UK Prime Minister Boris Johnson said he is "sticking by" Home Secretary Priti Patel despite her facing more bullying accusations.
It comes as a top official resigned over alleged abuse from her on Saturday.
At Prime Minister's Questions on Wednesday Ms Patel sat next to Mr Johnson as he was grilled by opposition Labour Party leader Jeremy Corbyn over abuse claims against her.
Since the resignation of Sir Philip Rutnam from the Home Office, officials in a further two departments have now made claims against her.
Mr Johnson said she was doing an "outstanding job" and he was "sticking by her".
Cabinet office minister Michael Gove confirmed on Monday that an inquiry into the allegations had been launched.
Sir Philip had said he had been the "target of a vicious and orchestrated campaign against him", which he alleged Ms Patel was involved in.
On Tuesday, Ms Patel sent an email to staff urging her team to "come together".
"We both regret Sir Philip's decision to resign," it said.
"We both deeply value the work that every person in this department does and care about the well-being of all our staff. It is therefore a time for us all to come together as one team."
On Wednesday she faced further accusations from staff in the Department for Work and Pensions and the Department for International Development.
She has denied that she bullied staff and Mr Johnson has asked officials to "establish the facts" by launching an inquiry into the allegations.
Sir Philip has vowed to sue for constructive dismissal.
Some staff from the Department for International Development, which she headed between 2016-17, claimed she subjected members of her private office to abuse.
