British Prime Minister Rishi Sunak is facing pressure from the Opposition on Wednesday as one of his close allies and embattled ministers resigned from the Cabinet pending an investigation into allegations of bullying against him. Sir Gavin Williamson, who was minister of state without portfolio as of yet was accused of abusive behaviour towards fellow Conservative Party colleagues and civil servants after which he posted his resignation on Twitter. Sunak said he accepted Williamson's resignation "with great sadness" and thanked him for his "personal support and loyalty". "Your commitment to successive Conservative governments and the party over the years has been unwavering," he said. However, the Opposition has branded the episode as a sign of "poor judgement and leadership" by Sunak, and Labour Party Leader Sir Keir Starmer will use the weekly Prime Minister's Questions (PMQs) in the House of Commons to pile on further pressure over the issue.
