BBC News - Covid travel tests to be axed in England for double vaccinated
https://www.bbc.co.uk/news/business-60109945
People arriving in England from abroad will no longer have to take Covid tests if they have been fully vaccinated, the Prime Minister has confirmed.
Boris Johnson said the further relaxation of the travel rules was designed to show that the country was open to travellers and business.
He did not confirm when the current rules would be scrapped, but ministers are set to meet later on Monday.
