First Minister of Wales, Mark Drakeford, has told the Welsh Parliament that British Prime Minister Boris Johnson has not replied to his requests for travel restrictions to be imposed in areas of England with high levels of coronavirus.
"I have therefore asked for the necessary work to be brought forward, which would allow for devolved powers to prevent people from travelling into Wales from high-prevalence areas of the United Kingdom," he said.
Mr Drakeford said it was "important" to emphasise that it was not an issue regarding the border between Wales and England but a "matter of fairness".
"We've already heard from the First Minister of Scotland and she's eager to support what we're trying to do here. Now is the time for the prime minister to do the same thing," he told the Senedd.
"If he isn't willing to do so then the timetable is for us to use the powers in Wales by the end of the week."
