Welsh Labour politicians met on Monday night to discuss concerns around Vaughan Gething, BBC Wales has reported. Mr Gething is set to be named as Wales' new First Minister this week but his campaign was tainted by controversy over a £200,000 donation, which he says he will not repay and about which he refused to answer any meaningful questions during his campaign.

It was donated by a man convicted of environmental offences, whose company also wants to build a major solar farm on the outskirts of Cardiff, which the Welsh Government will have to approve due to its scale and nature. Mr Gething will be leading the Welsh Government when the decision is made. Another of his companies was fined £300,000 a few weeks ago over an employee's death.

Mr Gething's acceptance of the donation was described by former First Minister Carwyn Jones as "unfortunate" and he said Mr Gething had "lessons to learn". You can read more about how Mr Gething has responded so far here. A Welsh MP who backed Mr Gething has also strongly suggested she would have voted differently if she'd known about the donations. Llanelli MP Nia Griffith suggested on Radio Cymru's Bore Sul programme she would not have given Mr Gething her vote if she'd known about the source of the donations.

On Monday night, BBC Wales cited a source as saying there was a meeting of 14 politicians with the aim of trying to get across the "level of disquiet in the party". Mark Drakeford officially quits today, with Mr Gething taking over as first minister on Wednesday, when a vote will be held in the Senedd.

Mr Gething beat his only rival, the education minister Jeremy Miles, to become the first black leader of any European country on Saturday. Welsh Labour said Mr Gething achieved 51.7% of the vote compared to rival Jeremy Miles with 48.3%. In total, 57.8% of members voted and 9.4% of affiliates, giving an overall turnout of 16.1%.

The current minister for the economy, Mr Gething is expected to be declared the country's fifth leader since the National Assembly for Wales, now called the Senedd, was established in 1999.

A BBC Wales report says that one MS told them there was a "growing feeling in the Labour group that the donation should be returned, some even saying they won't vote for him on Wednesday if he doesn't". They added: "I can't see people following through on the threat. But with just 30 votes, unless the other parties abstain then all it takes is one Labour member to abstain to block it."

Mr Gething received two £100,000 donations from Dauson Environmental Group, whose director David Neal was given a suspended prison sentence in 2013 for illegally dumping waste on a conservation site. Four years later, Neal was prosecuted again for not removing it. In February, Atlantic Recycling was fined £300,000 after a worker was killed in a collision with a shovel loader vehicle at its Cardiff base.

Asked about anger in the party after his victory, Mr Gething said there was not a "cast iron" single view in the party that he had picked up on: "There will be different people having different views but the idea there's a single, cast iron view is not something I've picked up on with the calls I have made, and my team have made. That's not the view of the members within the party. What we need to do is to be clear about how united we're going to be moving forward, the way we all choose to behave, including me, and the government I form and how we stay a united campaigning force in a crucial year ahead of us."
