Boris Johnson will address the latest Partygate revelations for first time at Prime Minister's Questions today - as Rishi Sunak is absent from the Chamber.

The Conservative leader fields questions from MPs at midday after it emerged that Martin Reynolds, his Personal Private Secretary, invited more than 100 staff members to a "bring-your-own-booze" social drinks event at Downing Street during lockdown in May 2020.

But Mr Sunak, the Chancellor, will not be by the Prime Minister's side as he visits a pharmaceutical company in Ilfracombe - a four-hour drive away from Westminster - with Selaine Saxby, the backbench MP for North Devon.

Mr Johnson's big moment in the House comes after Tobias Ellwood, the Tory chairman of the defence select committee, urged him to "show some contrition" and use PMQs to apologise for the "poor judgement" of No 10.

Christian Wakeford, a Red Wall MP, warned ministers they cannot "defend the indefensible".

Yesterday, two poll found that a majority of voters want Mr Johnson to quit in the wake of the revelations. Angela Rayner, the deputy Labour leader, this morning described his position as "untenable".
