Wales' health minister has spoken of his disappointment after a deal to provide an extra 5,000 coronavirus tests per day collapsed.

Vaughan Gething said there had been a written agreement for the firm, who he refused to name, to increase testing capacity in the nation.

He told a press conference in Cardiff that there was "no getting away from the fact that those additional tests that we were due to have would have made an earlier difference for us".

Mr Gething said the Welsh Government was working now with other private organisations, the university sector and the NHS to increase the current testing capacity.

Within two to three weeks, this should increase to 5,000 tests per day and there will be a further 4,000 tests by the end of May due to UK-wide arrangements, he said.

He was speaking as Public Health Wales announced that 112 new cases had tested positive for Covid-19 in Wales, bringing the total number of confirmed cases to 1,563.

Seven deaths have been reported of people who had tested positive for the virus, taking the number of deaths in Wales to 69.

Mr Gething said: "We're absolutely not going to name the company that were due to provide 5,000 tests for Wales, we've been really clear about that.

"Our objective is to get more testing available and to focus on delivering that.

"We had a clear agreement for that company's team to come into Wales to set up the infrastructure required to provide those additional tests.

"I've always been clear about my disappointment that hasn't happened."

Mr Gething said the company had "made a decision" that they were unable to fulfil the agreement they had reached with the Welsh Government.

But he told the press conference that he wanted to focus on preparing the health and care system in Wales for the "difficult weeks ahead".

"There's no getting away from the fact that those additional tests that we were due to have would have made an earlier difference for us," Mr Gething said.

Adam Price, the leader of Plaid Cymru, urged the Welsh Government to explain why the deal had collapsed and who it had been with.

"Having blamed a company for walking away from vital deal on Covid tests I don't understand why Welsh Govt is refusing to say who and why - and especially if actions of UK Govt effectively scuppered Welsh deal meaning thousands of healthcare staff won't now be tested this week," he said on Twitter.

The number of deaths and confirmed cases of coronavirus fell in Wales in the figures announced on Tuesday.

A total of 112 new cases tested positive for Covid-19 in the Tuesday figures, compared with an increase of 210 on Monday.

Seven deaths were announced on Tuesday, half the number - 14 - announced on Monday.

Dr Giri Shankar, incident director for the novel coronavirus outbreak response at Public Health Wales, said: "It should be noted that while today's number of cases is lower than numbers previously reported, this should not automatically be considered a trend as case numbers can be subject to daily fluctuation."

He repeated that coronavirus is circulating in "every part of Wales" and called on people to stay at home to protect the NHS.

The total number of confirmed cases, by health board area, are: 590 in Aneurin Bevan, 86 in Betsi Cadwaladr, 375 in Cardiff and Vale, 189 in Cwm Taf, 94 in Hywel Dda, 23 in Powys and 167 in Swansea Bay.

Thirteen cases are resident outside of Wales and the areas of 26 cases are yet to be confirmed.

Councils in the nation are being given new powers to increase hospital capacity to respond to the pandemic, housing and local government minister Julie James said.

The emergency permitted development rights will allow local authorities to change the use of buildings or erect temporary structures without planning permissions.

It means councils can use leisure centres as temporary hospitals if they are needed to prevent or control an emergency.

Up to 500 beds are being installed at Parc y Scarlets in Llanelli, while Cardiff's Principality Stadium will be converted into a 2,000-bed facility.
