People travelling from Spain to England or Wales will not have to undergo a 14-day quarantine from today, 10 July.
Spain was included on a list of 59 countries and 14 British overseas territories considered "lower risk" by the government in England last Friday, but it was unclear whether this would apply to Wales, Scotland or Northern Ireland.
However, on Thursday, the devolved government in Wales published the same list and first minister Mark Drakeford said the new regulations would also apply from today.
In contrast, however, Scottish first minister Nicola Sturgeon announced a modified list on Wednesday from which Spain and Serbia were omitted. This means those travelling from Spain into Scotland will still have to self-isolate for a fortnight.
The NI administration hasn't yet announced any lifting of restrictions.
