Deputy Prime Minister and Justice Secretary Dominic Raab is facing an investigation by senior lawyer Adam Tolley KC over allegations of bullying by dozens of officials.
Raab has declared that he has "behaved professionally at all times" and insists on "rebutting and refuting" the complaints.
The senior Tory MP is being investigated for eight formal complaints citing his behaviour as leading to weight loss, breakdowns, and suicidal thoughts for some staff.
The reports also revealed that some of the officials had been signed off work due to the stress they were under.
Dominic Raab has denied allegations of bullying by civil servants in his former department and as Brexit secretary.
A civil service union chief has told him to stop making public statements about the investigation.
The justice secretary told the BBC that he behaved professionally at all times, adding that the anonymous media reports about him are mostly incorrect.
Raab is facing an investigation by senior lawyer Adam Tolley KC over multiple bullying allegations made by dozens of officials, which he denies.
Mr Tolley has been appointed to investigate eight complaints lodged by civil servants in three departments, with sources suggesting his report could still be weeks from publication.
