Earlier this week Boris Johnson warned pub landlords would be able to refuse entry to customers if they have not received the Covid vaccination jab.

Speaking in Commons, the Prime Minister told MPs that it “may be up to the landlord”.

He said: “The concept of vaccine certification should not be totally alien to us.

“I think that’s the kind of thing that may be up to individual publicans. It may be up to the landlord.”

It is an approach which has caused controversy as Conservative MP and former minister Steve Baker warned it could create a “two-tier Britain” for those who are unable to take up the vaccine for medical reasons.

Trade body UKHospitality criticised the prospect of pubs and restaurants being subject to vaccine certificates as “simply unworkable” and said it could cause conflict between staff and customers.

Kate Nicholls, chief executive of UKHospitality, said: “It’s crucial that visiting the pub and other parts of hospitality should not be subject to mandatory vaccination certification.

“It is simply unworkable, would cause conflict between staff and customers and almost certainty result in breaches of equality rules.

“Through the success of the vaccine rollout we need to throw off the shackles of coronavirus in line with the Government’s roadmap, not impose more checks on our ability to socialise and do business.”

The Prime Minister sought to calm fears over the possible introduction of coronavirus health certificates as publicans criticised plans which could see landlords demanding to see drinkers’ papers before letting them have a pint.

Mr Johnson acknowledged the “moral complexities” around a domestic vaccine passport scheme and suggested that it might only be possible to introduce one after all adults had been offered a vaccine at the end of July.

The Government is poised to reveal plans next month on either April 5 or April 12.

Brits could have three ways of getting a “freedom pass” to enjoy a pint at the pub from April 12, according to reports.

Pubs will welcome punters for outdoor drinking and proof of vaccination, a recent clear test, or a previous Covid infection are three things that could see you allowed to enter.

The Government will say more on the possible use of Covid status certificates in early April, and suggested they could also be based on whether individuals have developed antibodies through infection, as well as vaccinations and negative tests.

But landlords rejected their use after his earlier suggestion it could be up to them to decide whether to screen customers’ certificates on entry, ahead of fresh details emerging of a possible incentive for pubs to adopt the measure.
