A ban on people from the UK's coronavirus hotspots travelling to Wales would be 'unenforceable", police have warned.
The Police Federation of England and Wales said there would be difficulties identifying where people were travelling to and from and the force is already "overstretched".
Welsh First Minister Mark Drakeford announced on Tuesday that measures to stop those from areas of England, Scotland and Northern Ireland with high levels of coronavirus entering Wales would be put in place by Friday, if Boris Johnson did not impose UK-wide travel restrictions.
However, Mark Bleasdale, Welsh lead for the Police Federation of England and Wales, criticised the move.
Mr Bleasdale warned that the move would only add to the police's difficulties.
“On the face of it, this is unenforceable because of the difficulty of identifying where people are coming from and where they are going to", he said.
“There will also be plenty of individuals travelling legitimately from areas which are not high risk, and this will only add to the other difficulties officers face when policing the existing regulations.
“Some areas of Wales are already in lockdown, and many individuals are already unable to travel in and out of counties unless they have good reason.
“In other locations, provisions are more relaxed, so this proposed travel ban adds yet another level of complexity to policing.”
Mr Bleasdale added that police forces in Wales were already “overstretched” due to the pandemic and that crime had returned to normal “pre-Covid levels”.
“We would ask members of the public to continue to be supportive and realise this is an extremely challenging period for frontline officers,” he said.
“My colleagues will continue to do their utmost to protect the public in their usual professional manner.”
