I see the narrative has changed now. See: https://www.bbc.co.uk/news/articles/crgg0035dd0o
This a quote from the article:
Earlier on Saturday, a Labour MS said: "Vaughan Gething and his supporters made the case that the attacks against him were racially driven and that he was being held to a higher standard than others."
The MS added: "His supporters remain loyal but the group is still split."
However, an individual in the Welsh government itself strongly denied that Mr Gething had made such comments, and said they had instead come from Labour Members of Senedd (MSs).
He appears to be distancing himself from the original comment, so who really knows the truth?
