Labour MP Ann Clwyd has disputed claims by First Minister Carwyn Jones that she did not give the Welsh government facts or evidence to back up her concerns about the Welsh NHS.
Mr Jones had said Ms Clwyd had provided "anonymous" and "unattributable" comments that "can't be investigated".
But the Cynon Valley MP said although the identity of those patients had been protected in some cases, she had provided Mr Jones with a summary list of the complaints raised.
She also met him to outline the allegations made and had written a "comprehensive letter" to him on the matter, she said.
Ms Clwyd spoke to BBC Wales' parliamentary correspondent David Cornock.
