Rishi Sunak remains confident in his deputy after an investigation into Dominic Raab’s behavior was expanded to include a third formal complaint filed against him.
The latest claim concerns Mr Raab’s tenure in the now-defunct department for leaving the European Union, Downing Street said.
It will be considered along with two other formal complaints against the senior minister about his previous work at the Ministry of Justice and the Ministry of Foreign Affairs.
No. 10 said it is clear that the most recent accusation was received by the cabinet on Wednesday.
Mr Sunak asked for the scope of the investigation on Thursday evening after receiving “required advice” from the department.
A spokeswoman for No 10 said: “I can confirm that the Prime Minister has now asked the investigator to add another formal complaint regarding conduct at the Department for Exiting the European Union and to establish the facts in accordance with the existing job description. ”
When asked if Mr. Sunak still has faith in Mr. Raab, she said, “Yes, he has.
“An independent investigation is now underway. It is led by someone with extensive experience in this field. We are not going to pre-empt or condemn that process.”
Deputy Labor leader Angela Rayner demanded that the scope of the inquiry be expanded to “enable proactive investigation” into Mr Raab’s conduct.
“The drop-drop-drop-drop of serious complaints about his deputy shows that he can no longer turn the tide,” she said.
“Rishi Sunak’s attempted bonding will not fool anyone.”
It comes after a source confirmed on Thursday that several senior officials who worked closely with Mr Raab were preparing to make further formal complaints, as first reported by BBC’s Newsnight.
The allegations, if filed, could feed into the investigation being conducted by senior attorney Adam Tolley KC.
Mr Raab asked for the independent inquiry last week after two bullying complaints were filed against him.
The Lib Dems have warned that the “flood of allegations” about Mr Raab’s conduct cannot be “swept under the carpet”.
The party’s chief whip Wendy Chamberlain said: “Rishi Sunak must confirm that he will sack Raab if these complaints are upheld.”
