British Prime Minister Rishi Sunak was roundly criticised by political rivals on Friday, hours after apologising for leaving D-Day commemorations in France early in the latest self-inflicted setback to his stuttering general election campaign. "What happened was completely wrong and the prime minister has rightly apologised," she said, before adding it should not become "a political football". In his apology, Sunak insisted he "cares deeply about veterans" and noted his attendance at two D-Day memorial events this week. But it's also a very important moment to show that you're being prime ministerial," Craig Oliver, the former adviser to Cameron when he was prime minister, told BBC radio. Sunak, an internal Tory appointee as prime minister in October 2022, called the election in a widely-mocked, rain-sodden speech from Downing Street last month.
