The deputy PM insists Boris Johnson's 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.

Number Ten strongly denies Mr Johnson lied.

An investigation's already examining a number of Downing Street parties.

Esher and Walton MP Dominic Raab is refusing to comment about whether the PM should resign.
