Plaid Cymru has ended its co-operation agreement with the Welsh Labour government with immediate effect, party leader Rhun ap Iorwerth has said.

He cited concerns over First Minister Vaughan Gething’s election campaign finances as a factor, claiming the receipt of £200,000 from a company convicted of environmental offences “demonstrates a significant lack of judgment”.

Mr ap Iorweth also said he was worried about the First Minister’s decision to sack his minister for social partnership, Hannah Blythyn, following the leak of a phone message to the media which she insisted she was not behind.
