The Welsh government are undertaking a “detailed planning” in preparation for a potential short national lockdown.
The Welsh government will take a look at the coronavirus figures this week and then decide what next steps to take.
Speaking to Sky News Kay Burley, the Welsh First Minister Mark Drakeford said that a “circuit breaking period” could be the “most effective way of turning back the tide of coronavirus.”
He said, “We want to act now in order to prevent the worst from happening, to give us a better chance of getting through the rest of the autumn and the winter.
“If a circuit breaker is the right way to do it then that is what we will do and we’re very actively talking about and preparing for that should it be necessary.”
Drakeford said that it is “not sensible” for Prime Minister Boris Johnson to dismiss a second national lockdown.
He added, “They ought to sit down with everybody, look at it seriously and then make a proper decision.”
Work and Pensions Secretary Therese Coffey played down a second national lockdown.
Coffey told Sky News, “I don’t believe that is the case but as I say this will continue to be a decision that the prime minister will lead on.”
People across areas that are under local lockdown in Wales are not allowed to travel to other parts of the country.
Drakeford said, “It is a simple, straightforward, practical action that prevents the flow of the virus out of areas where there is a great deal of it into areas where there is very little of it, and I’m baffled why the prime minister continues to resist this idea.
“All we’re asking is for fair play, for people in high volume areas outside Wales not being able to do things that people in Wales who live in high coronavirus areas are already prevented from doing.”
