A Labour politician has said she does not know if Vaughan Gething can carry on as first minister after he lost a confidence vote.
Jenny Rathbone, MS for Cardiff Central, said it was a "very uncertain environment and we'll have to wait and see".
Her comments ahead of a meeting of members of the Welsh Parliament's groups of Labour politicians.
BBC Wales have been told it is expected to take place on Friday.
Vaughan Gething lost a vote of no confidence on Wednesday after two of his Labour Senedd members were absent through illness.
It follows months of rows caused by the donation of £200,000 from Dauson Environmental Group, owned by a man previously convicted of illegally dumping waste.
Ms Rathbone told BBC Radio Wales Drive that the "reputation of the Senedd is at risk" and that accepting money from people convicted of environmental offences "is a problem".
She said the issue had been raised on the doorstep.
Asked if Mr Gething could brush off the defeat and carry on as before, she said: "I don't know. It's a very uncertain environment. We'll have to wait and see."
"It is uncomfortable because we've all been dragged into this," she said.
Pressed on whether the first minister had the confidence of the Senedd, Ms Rathbone added: "Well, he lost the vote. That's on the public record. I think you'd have to address your remarks to him."
Jenny Rathbone had offered to lend Mr Gething money so he could repay the controversial donations made to his campaign.
Mr Gething has declined to repay the cash.
In an earlier interview she said: “I don’t think it is wise to be taking money from a convicted criminal, and therefore I think it’s important that we enable this money to be repaid if that is what Vaughan Gething wishes to do."
A party colleague, Vikki Howells, said on Thursday it would have been a breach of the ministerial code for Mr Gething to have taken such a loan.
