Tory MP for Winchester Steve Brine has once again been urged to call for Boris Johnson's resignation amid the latest revelations surrounding 'partygate'. 

This comes after senior official Sue Gray found "failures of leadership and judgement" in a damning, redacted summary of a growing list of alleged gatherings she had deemed necessary to investigate.

Boris Johnson has come under renewed pressure over lockdown parties in Downing Street, amid reports he attended more gatherings under investigation by the police.

The Daily Telegraph reported that he was seen heading up to his flat on the night of a gathering there which the Met is investigating.

The Prime Minister is also said to have spoken at two more leaving dos which are the subject of Scotland Yard inquiries.

The reports are likely to fuel claims by opposition parties that Mr Johnson was well aware of the so-called “party culture” in Downing Street and parts of Whitehall at that time.

Liberal Democrat parliamentary candidate for Winchester and Chandler's Ford, Danny Chambers, previously wrote to Mr Brine in January, calling for the MP to push for the Prime Minister's resignation.

He has now renewed his message to Mr Brine, insisting he must do the "honourable thing" and call for Boris Johnson to go.

Responding to Sue Gray’s update on parties being held in Downing Street during Covid lockdowns, he said: "This is a damning moment for Boris Johnson.

"While people in Winchester & Chandler’s Ford made terrible sacrifices during lockdowns, Boris Johnson and his team were partying in Downing Street.

"We all have painful memories of that lockdown, from not being able to see dying relatives, to being separated for months on end from our friends and family.  

"It is time for Steve Brine to do the honourable thing and call for Boris Johnson to go."

Mr Brine yesterday labelled the revelations an "embarrassment", but insisted he would not discuss "private correspondence". 

He said: "This whole episode is an embarrassment and a distraction from extremely serious international and domestic events.

"While the Sue Gray update may be thin at present, it’s pretty damning on the culture at No.10 and from her language it seems probable there’s a lot more to come when the police allow it.

“I wouldn’t be at all surprised if more revelations follow between now and then but, either way, I expect publication in full and major changes at No.10.

“I never discuss private correspondence, but I have always thought self-awareness is a much under-valued quality in a leader and will be making that point this week.”

Mr Brine failed to confirm whether he had sent a letter to the 1922 Committee expressing no confidence in his party leader, or whether he intended to do so. 

However, he did reveal he will be sitting down for a one-on-one "chat" with the Prime Minister this evening at his request.

The MP also said he would continue to respond to each and every concerned constituent who wishes to write to him.
