Travel bosses have called for the rules to be eased as soon as possible.Covid: International travel changes for fully vaccinated people to be set out
Details about how and when fully vaccinated travellers can return from certain countries without having to quarantine are to be set out later.
Transport Secretary Grant Shapps will make a statement to MPs this morning.
Currently, those arriving in the UK have to follow strict rules regardless of their vaccine status, and anyone returning from countries on the amber or red list must isolate for 10 days.
The government has already said it was planning to scrap the need to quarantine for those who are double-jabbed and returning from amber countries.
But it has not set out how it would work, when it would happen, and whether unvaccinated children would also be able to avoid quarantine if their parents are fully vaccinated.
In addition to relaxing the rules around isolation for travellers, Chancellor Rishi Sunak told the BBC that the health secretary was considering a “more proportionate and balanced approach” to isolation for Covid contacts.
