The controversy surrounding donations to Vaughan Gething’s leadership campaign has hit the headlines once again, as opposition party leaders have called for an independent investigation.

£200,000 was given to Mr Gething by the director of Dauson Environmental Group Ltd, David Neal, who was convicted twice for environmental offences.

Neal was given a suspended prison sentence in 2013 for illegally dumping waste on a conservation site on the Gwent Levels. His companies Atlantic Recycling and Neal Soil Suppliers were also prosecuted and ordered to pay fines and costs of £202,000.

Speaking to BBC Politics Wales on Sunday, cabinet minister Jeremy Miles MS, said that he “would not have accepted” the donation.

Also revealed over the weekend was the loan that Dauson Environmental Group Ltd had received from the Development Bank of Wales, a bank owned by the Welsh Government.

It has prompted the leader of Plaid Cymru to call for a “wholly independent external investigation” into “unanswered questions” surrounding the donations.
