Britain's deputy Prime Minister insists Boris Johnson has been "straightforward" and did not lie to Parliament about drinks at Number Ten in breach of lockdown rules.
Former Downing Street adviser, Dominic Cummings, alleges the Prime Minister knew about the party in May 2020 before it happened - despite claiming otherwise.
An investigation is already examining a number of Downing Street parties.
Dominic Raab is refusing to comment about whether the PM should resign.
"I'm not going to speculate on hypothetical scenarios.
"What I am going to do is recognise the importance of the public frustration with any perception and any reality of double standards and let Sue Grey do her job. That's the right thing to do."
