Pressure on UK PM Boris Johnson to resign is growing after his former close adviser claimed he was warned about holding parties during lockdowns at the start of the pandemic. Dominic Cummings was with Johnson when the prime ministership was just a twinkle in Johnson’s Brexit campaigning eye, and was working for him when he attended a Downing St drinks party in May 2020. News of his attendance leaked to the media and Johnson apologised to Parliament last week. But Cummings disagrees. “He knew he was at a drinks party ‘cos he was told it was a drinks party, and it was actually a drinks party,” he wrote in his blog. Cummings has been relentlessly negative about Johnson since he was forced out in late 2020, and hasn’t been backwards in coming forward on his former boss’s shortcomings. Overnight, Johnson “categorically” denied he was warned that a drinks party in the No 10 garden risked breaking lockdown rules. “I would have remembered that,” he said.
