The British government’s culture secretary has held talks with the BBC as the broadcaster comes under growing scrutiny after one of its TV hosts drew an angry backlash for dismissing sexual misconduct allegations made against him. Gregg Wallace, a long-time co-presenter on the popular cooking contest show “MasterChef,” has been accused by multiple women of making inappropriate sexual comments and behaving inappropriately on set over 17 years. Wallace said last week he was stepping away from the show while an investigation was launched into his alleged behavior. But his case received further attention Sunday when he said on social media that the complaints against him came from “a handful of middle-class women of a certain age.” Wallace issued an apology on Monday.
