Labour leader Sir Keir Starmer has said he will step down if he receives a fixed penalty notice.
He has come under pressure over an event in Durham in April 2021 with party colleagues when he was filmed having a drink and a takeaway curry was ordered.
At the time, COVID rules banned household mixing indoors, apart from working.
Sir Keir has said he was working and stopped to eat.
He said during a news conference: “I believe in honour, integrity and the principle that those who make the laws must follow them.”
He added: “I believe that politicians who undermine that principle undermine trust in politics, undermine our democracy and undermine Britain.
“I am absolutely clear that no laws were broken. They were followed at all times. I simply had something to eat while working late in the evening, as any politician would do days before an election.
“But if the police decide to issue me with a fixed penalty notice I would, of course, do the right thing and step down.”
Sir Keir said: “This matters, it matters because the British public deserve politicians who think the rules apply to them.
“They deserve politicians who hold themselves to the highest standards… and who put the country first rather than themselves.
“They will always, always get that from me.”
