Nigel Farage has been accused of breaching the UK's quarantine rules after posting a photo in a pub today - less than two weeks after returning from the US.

The acting leader of the Liberal Democrats, Sir Ed Davey, has written to Kent Police asking them to investigate whether the Brexit Party leader Nigel Farage has broken coronavirus quarantine rules.

56-year-old Farage tweeted a picture of himself on so-called 'Super Saturday' a day which saw many businesses, including pubs, in England reopened.

He shared an image to his followers with the caption: "12 o'clock, first customer in. Love it."

Exactly a fortnight ago, Mr Farage tweeted from a trip to the United States - where he was a guest at a rally for President Trump.

People travelling to the UK from the US are required to quarantine for a period of 14 days from the moment they arrive.

In a statement, Sir Ed Davey said: "There are clearly serious questions to answer for Nigel Farage," 

"It is clear from his social media posts that he was in America on 20 June, and he was pictured at a Trump rally that evening. Given the current requirements for visitors returning to the UK to isolate for 14 full days on their return, Nigel Farage appears to be in violation of the quarantine," he added.

"By choosing to go to the pub when it appears he should have been staying at home, Mr Farage is showing a flagrant disregard for the safety of people in his community."

It is understood that the letter has also been sent to Home Secretary Priti Patel. 

It reads: "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."

MSNBC footage shows Mr Farage at a Donald Trump rally in Tulsa, Oklahoma, at 1.02am on 20 June.

Nigel Farage insists however that he has "been back from the USA for two weeks."

Writing on Twitter, Alexandra Phillips, a former Brexit Party MEP who once worked as Nigel Farage's media adviser, 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."
