Rishi Sunak, the UK Chancellor of the Exchequer, is facing pressure to clarify what he knew about the allegations of Dominic Raab's bullying before he was appointed the Deputy Prime Minister.
The Prime Minister Boris Johnson has refused to suspend Mr Raab while an investigation into the allegations is ongoing.
Despite this refusal, some Conservative MPs have called for the inquiry to be expedited, highlighting that everyone would benefit from a speedy completion of the investigation.
The pressure comes amidst a rising number of allegations against Mr Raab, and Tory MPs have indicated that Raab's position may become untenable if found guilty.
In light of the accusations of bullying against Dominic Raab, Rishi Sunak is being called to answer whether he was aware of informal complaints about Mr Raab's behaviour before Mr Johnson appointed him to the cabinet.
While Boris Johnson has resisted calls from Tory MPs to suspend Raab pending an investigation, some Conservative MPs want the inquiry to be expedited.
Meanwhile, the allegations against Raab continue to mount, with the number of civil servants lodging complaints ranging from 3 to 24, depending on the source.
Despite this, Mr Raab is expected to keep lobbying to retain his position as Deputy Prime Minister.
The news follows large-scale investigations into accusations of bullying within Downing Street that have exposed a toxic culture led by some of the most senior officials in government.
