On 15 July 2020, it was reported that Chris Grayling had failed to secure the nomination as Chair of the committee. Acting against the Conservative Whip, Julian Lewis was elected Chair by the members of the ISC. As a consequence, he had the Conservative Whip temporarily removed. A ‘senior government source’ told the BBC that Dr Lewis "has been told by the chief whip that it is because he worked with Labour and other opposition MPs for his own advantage". Grayling subsequently resigned from the Committee on 28 August. Bob Stewart has been appointed as Grayling's replacement.
