Rishi Sunak still has faith in his deputy after an investigation into Dominic Raab’s conduct was expanded to include a third formal complaint against him.
The latest allegation relates to Mr Raab’s tenure in the now defunct department for exiting the European Union, Downing Street said.
It is being examined alongside two other formal complaints against the Prime Minister regarding his previous positions at the Ministry of Justice and the Foreign Office.
No 10 said it was aware the latest allegation was received by the Cabinet Office on Wednesday.
Mr Sunak asked to update the scope of the investigation Thursday night after receiving “necessary advice” from the department.
A No10 spokeswoman said: “I can confirm that the Prime Minister has now asked the investigator to add a further formal complaint regarding the conduct of the Department for Exiting the European Union and the facts in line with existing duties to investigate. ”
When asked if Mr Sunak still had faith in Mr Raab, she said: “Yes, he does.
“There is now an independent investigation that is ongoing. It is run by someone who has extensive experience in the field. We will not anticipate or anticipate this process.”
It comes after a source confirmed on Thursday that several senior officials who had worked closely with Mr Raab were preparing to file more formal complaints, as first reported by Newsnight.
The allegations, if made, could be included in the investigation being conducted by lead counsel Adam Tolley KC.
Mr Raab requested the independent inquiry last week after two bullying complaints were made against him.
The Liberal Democrats have warned that the “deluge of allegations” about Mr Raab’s behavior cannot be “swept under the rug”.
The party’s chief whip, Wendy Chamberlain, said: “Rishi Sunak must confirm that he will fire Raab if these complaints are upheld.”
