In case anyone is tempted to sneak off for an Easter break to one of the countries that have declared themselves open to vaccinated Brits, the Government has made it illegal to leave the country for non-work reasons from March 8th. In guidance published yesterday, it states:
From March 8th 2021, you must complete this form to declare the reason that you need to travel abroad.
You must complete this form if you are travelling outside the UK from England. Different rules apply for international travel from Northern Ireland, Scotland and Wales.
You don’t need to complete the form for travel within the UK, to Ireland, the Channel Islands or the Isle of Man.
You should print a copy of the completed form or save it to a mobile phone or other device.
You may be asked to show this declaration form at the port of departure. You may carry evidence to support your reason for travel.
Entering a port of departure to travel internationally without a completed form is a criminal offence, for which you could be fined.
If you try to travel abroad without a legally permitted reason, you may also be fined for breaching the stay at home requirements.
