Thanks to Mike Prior for sending me this.
Travelling internationally from England
There are no longer any restrictions on leaving England to travel internationally, however to protect public health in the UK and the vaccine rollout, you should not travel to countries or territories on the red or amber lists.
If you travel to one of these countries or territories, you should look at the rules in place at your destination and the Foreign, Commonwealth and Development Office (FCDO) travel advice. You should do this even if you are returning to a place you’ve visited before.
