POLL: Do you believe Boris Johnson or Dominic Cummings over the Downing Street 'drinks party' held on May 20, 2020?
Boris Johnson's former top aide Dominic Cummings says he warned the Prime Minister about Number 10 holding a drinks party in the garden during lockdown.
Mr Cummings claims the PM "waved aside" concerns about the gathering.
Downing Street insists it was "untrue" to say Mr Johnson was "warned about the event".
Mr Johnson has admitted he attended the event on May 20, 2020, but says he believed it was work-related.
Who do you believe?
