The acting leader of the Lib Dems Sir Ed Davey has written to Kent's police chief asking to investigate whether Nigel Farage broke lockdown rules by visiting the pub on Super Saturday.
Mr Farage posted a picture of himself with a pint on Twitter, with the caption: "12 o’clock, first customer in. Love it."
However, Mr Farage had attended a rally for Donald Trump in Tulsa a fortnight ago. Sir Ed requested that the police establish a timeline of events to ensure that Mr Farage had quarantined for 14 days after his return from the US.
Sir Ed wrote to Kent's chief constable, Alan Pughsley: "I write to ask you to immediately investigate this issue, establish the timeline of events for Mr Farage's return to the UK and establish whether Mr Farage was in breach of his quarantine. It is vital that lives are not put at risk by breaches of quarantine.
"I am copying this letter to the home secretary as I believe this case illustrates the difficulties that the police and Home Office will have in enforcing the quarantine rules as they are currently set out."
To all those screaming and shouting about me going to the pub.... I have been back from the USA for 2 weeks and I have been tested — the result was negative. Sorry to disappoint you. Cheers! pic.twitter.com/E8maRljGwS— Nigel Farage (@Nigel_Farage)July 4, 2020
Mr Farage wrote on Twitter that he quarantined for two weeks and had a negative Covid-19 test after his trip to the US.
As coronavirus cases continue to surge in the US, those who travel from the country to the UK must self-isolate for 14 days.
Alexandra Phillips, a former Brexit Party MEP who once worked as Nigel Farage's media adviser, defended Mr Farage on Twitter.
She said: "Dear Ed Davey, The police have better things to do, you sad little man.
"Getting an officer to go to Nigel's house to tell him he shouldn't have gone to the pub is a total waste of resources and makes you look like a pathetic, attention-seeking twerp."
