Idea raises concerns among some scientists who say it could fail to stop new variants entering country
Potential plans to introduce a traffic light scheme for travel abroad have prompted concerns among scientists that the approach is too simplistic and could fail to prevent new variants from entering the UK.
At present, it is illegal to travel abroad for holidays, with foreign travel only allowed in specific circumstances. Those who do travel abroad must quarantine either at home or in a hotel on return to England. All must do so in a hotel on return to Scotland.
