At present, Britons are being advised not to travel to "amber list" countries - including popular hotspots such as Spain and France - as government guidelines state they must quarantine at home for 10 days after upon return.
The introduction of relaxed rules for vaccinated Britons could mean breaks to amber list countries would be permitted as the summer holiday season begins.
It could also encourage more people to get vaccinated and would serve as a boost for the troubled travel industry, which has struggled to operate under the restrictions and their changing nature.
