UK PM Boris Johnson was warned against lockdown party, says former advise

The UK’s Prime Minister Boris Johnson was warned about No 10 holding a drinks party in the garden during lockdown, the prime minister's former top aide Dominic Cummings says.

Mr Cummings - who has been strongly critical of Mr Johnson since he left No 10 - says the PM "waved aside" concerns about the gathering.

Mr Johnson has admitted he attended the event on 20 May 2020, but says he believed it was work-related, and Downing Street said it was "untrue" to say Mr Johnson was "warned about the event".
