to enter hospitality premises without restrictions, as well as vaccines and negative tests, he said, could be previous coronavirus infections, should health certificates be adopted.

However, he added: "No decisions have been taken at all."
After a year of lockdowns and restrictions, not everyone is against the idea of vaccine passports
Reacting to the Prime Minister's suggestion yesterday, UKHospitality chief Kate Nicholls said: "It's crucial that visiting the pub and other parts of hospitality should not be subject to mandatory vaccination certification."
She called the proposal "simply unworkable," and said that it would undoubtedly would "cause conflict between staff and customers and almost certainty result in breaches of equality rules."
Among the general population, there is no consensus as to whether the suggestion would be a great idea or a terrible one, as fears of discrimination and poor implementation on the one hand are mitigated by restless Britons ready to return to public houses at whatever cost.
Our polling wasn't clear cut either, as respondents to our polls on Twitter and Instagram were almost equal on each side of the debate of whether the introduction of vaccine passports might be worthwhile if it meant that they could operate without restrictions.

This afternoon, the government is set to vote on extending emergency Covid regulations until September 25th, which could see the extension of restrictions past June 21st should efforts to contain the virus be delayed further.
