Dominic Raab has vowed to quit if he is found guilty of bullying staff.
The deputy prime minister is facing an ongoing investigation into how he treated a number of government officials.
However, he refused to step down ahead of the investigation into his behaviour, saying “innocent until proven guilty”.
Staff from multiple departments he has worked in have made complaints about his behaviour – including at the Brexit department, foreign office and ministry of justice.
He is being investigated by senior lawyer Adam Tolley KC, with dozens of officials thought to be involved in eight formal complaints.
Raab told Sky’s Sophy Ridge On Sunday programme: “I’m not going to start speculating on what the outcome might be. Again, you’re asking me to comment on the subject matter.”
The justice secretary dismissed calls to stand aside while the probe is carried out but added: “Allow me to respond in the right way at the right time, of course. Look, if an allegation of bullying is upheld, I will resign.”
Former Tory chair Jake Berry has called on Raab to step aside from his ministerial roles while he is investigated over the claims.
