Keir Starmer is considering whether to commit to resigning if police find he broke coronavirus rules as he battles to regain the political initiative while pressuring Boris Johnson over his own fine.
The Labour leader was understood to be in talks on Monday about whether to announce the pledge, after pulling out of a scheduled event where he would have faced fresh questions.
Allies insisted he was not “ducking scrutiny” by cancelling his attendance at the discussion, as he is investigated by police over the Durham beer-and-curry gathering in April last year.
Mr Starmer was facing pressure to set out his position, having called for the resignation of the prime minister and chancellor Rishi Sunak after they were fined for a Covid breach.
A pre-emptive announcement on his future if he too is fined would enable him to continue calling for Mr Johnson to leave Downing Street while himself under investigation.
Mr Starmer was set to make a televised statement at 4pm.
He had been due to speak at an Institute for Government discussion, but pulled out on Sunday, with Labour not explaining why other than to say “plans change”.
Mr Starmer also did not attend a memorial service for former MP James Brokenshire at St Margaret’s Church in Westminster, where he was expected join politicians from across the divide including the prime minister and Cabinet members.
Labour says the food was consumed between work events, meaning it was within the rules despite the ban on indoor socialising.
But the Labour leader was facing calls to answer fresh questions after a leaked memo suggested the takeaway was planned, with no further work apparently scheduled after dinner.
Shadow health secretary Wes Streeting said he did not know why Mr Starmer cancelled his appearance at the event but insisted he was not avoiding scrutiny.
Mr Streeting told BBC Breakfast: “I have no idea why he cancelled the event and I certainly didn’t ask before I came on because I think it’s such a trivial issue.
“The idea that Keir has been dodging questions… I mean he’s been out all weekend, even after a local election campaign where we did very well, he’s been out thanking Labour teams, particularly in the places that we did particularly well in these elections.”
Mr Streeting added that Mr Starmer has faced journalists “wherever he’s been”, including as recently as Saturday, adding: “The idea that Keir is somehow ducking scrutiny is simply not true.”
Conservative universities minister Michelle Donelan accused Mr Starmer of hypocrisy, having pressured Boris Johnson over Downing Street lockdown breaches, for which the prime minister was fined by police.
Asked if the Labour leader should resign if fined, she told Sky News: “I think this is a decision for him, he’s going to have to search his soul after making this a top priority over the last few months at the expense of key issues like the rising cost of living, etc, but look, this is a decision for him.
“My takeaway is that it does smack of sheer hypocrisy.”
Some 46 per cent of people believe Mr Starmer should resign if he is fined by police, according to a YouGov survey of 1,674 adults over the weekend.
That includes 48 per cent of those who voted Labour at the last election, which is higher than those who voted Tory, at 40 per cent.
With the police investigation continuing, 54 per cent responded that Mr Starmer either probably or definitely broke the rules.
Labour MP Mary Foy denied reports that staff were drunk at the event, held in the City of Durham MP’s constituency office.
In a statement, she said: “These allegations about my staff are untrue.
“I have already said that I and my team were working during a very busy period, including facilitating the leader’s visit. I do not believe either I or my office staff broke any rules.”
Pressed on why Mr Starmer pulled out of Monday’s discussion, a Labour spokesman said: “Plans change.”
At the time of the Durham gathering, non-essential retail and outdoor venues, including pub gardens, were open, but social distancing rules, which included a ban on indoor mixing between households, remained in place.
Mr Starmer previously said no restaurants or pubs were open at the time of the alleged breach so “if you didn’t get a takeaway then our team wasn’t eating that evening”.
Labour has indicated that as Mr Starmer was working, the meal did not constitute a social event.
Mr Starmer a former director of public prosecutions, told reporters on Saturday: “As I have explained a number of times, I was working in the office, we stopped for something to eat.
“There was no party, no breach of rules, I am confident of that.”
He said he would not resign and would lead Labour into the next general election.
