Mr Gething said: “Unfortunately, we have seen a rise in coronavirus cases in four north Wales local authority areas – in Denbighshire, Flintshire, Wrexham and Conwy.

“These are largely linked to people socialising indoors and are the pattern of transmission similar to what we have seen in South Wales.

“We have worked closely with local authority leaders and the police in North Wales and we all agree about the need to take swift action to control the spread of the virus.”

Under the rules, nobody is able to enter or leave the counties without a "reasonable excuse".

Exceptions include travelling to school or to work if you are unable to work from home.

People can travel to buy food and medical supplies, seek medical assistance or go to the vets, and move home.

Gwynedd and Anglesey will not be included in the lockdowns at this stage.

Mr Gething said there were no plans for no more restrictions on a national level.
