There is increasing hope among ministers and officials that foreign holidays may be possible this summer, it is understood.
The Government is reportedly considering the creation of globally recognised vaccine passports, which could allow people to travel.
It comes as the Greek tourism minister revealed on Thursday that his government is in “preliminary discussions” with UK ministers over a potential travel agreement for vaccinated Britons.
Speaking on BBC Radio Four’s Today programme, Haris Theoharis suggested that restriction-free holidays could be on the cards for those who have been vaccinated.
He said he was hoping for a “semi-normal summer” this year, and said that a ‘vaccine passport’ scheme would facilitate travel between Britain and Greece.
