A national lockdown in Wales cannot be ruled out.

That is the message from Wales' Heath Minister Vaughan Gething who is considering restrictions for the whole country as a way of dealing with the “increasing tide of confirmed cases” in Wales.

Across Wales, the closely-watched seven day infection rate has now risen to 27.2 for every 100,000 people. Caerphilly and RCT are already in local lockdown.

And the areas of Bridgend, Blaneau Gwent and Merthyr Tydfil are being closely monitored for rising rates of coronavirus.

The weekly rate of infection is now highest in Merthyr Tydfil with 94.5 cases per 100,000 people - a slight drop from yesterday's figure of 96.1.

Professor Chris Whitty, England's chief medical officer, is giving a press conference this morning at 11am to warn the pandemic is at a critical point. You can follow live updates from that and from Mr Gething's press conference at 12.30pm here.

Mr Gething told BBC Radio Wales there was a “limited period of time” to improve the situation as infections were moving younger to older people.

He indicated that further local lockdown restrictions might be imposed this week.

"We know the tide is increasing. We know it is spreading in different parts of the country but the intensity is in particular in the south-east part of Wales.

"We will have to make more choices this morning. There will be more figures available to me. And I will have to take on board the advice and take a decision with the First Minister but it it entirely possible that more restrictions could happen this week."

Talking about a national lockdown for Wales, he said: “That decision is not imminent today.

“It is always possible. The reality is that we have limited period of weeks, and we have to make choices each and every day about whether local restrictions are required.

"If we get to the point that we have a significant group of restrictions, we look at whether a regional approach is needed, or whether we actually need to take a national approach.

“Going back to February, if we understood what we know now, we would have acted earlier.

"We wouldn’t have waited until March 23, if we had seen infection rates as they were. We would have avoided lots of harm.

“The challenge then is the economic harm of coronavirus, and that produces health harm too.

"A proper understanding of what the UK Government is prepared to do for people to support the economy with jobs. That is really, really important for all of us.”

His warning comes ahead of the address to the nation by Professor Chris Whitty.

He is expected to say that the UK stands at a "critical point" in the coronavirus pandemic.

The chief medical officer for England will potentially lay the ground for tough new controls in an urgent attempt to halt the surge in infections.

In a televised briefing on Monday at 11am, he will say the country faces a "very challenging winter", with the current trend heading in "the wrong direction".

Boris Johnson spent the weekend with senior ministers and advisers discussing what action to take as the rise in the number of new cases showed no sign of slowing.

It is thought the Prime Minister could set out new measures, including potentially a two-week lockdown for England in October, in a press conference as early as Tuesday.
