A former colleague of Carl Sargeant has said something is wrong with the system to deal with allegations against MPs if someone could die as a result of its emotional impact.
Sargeant is understood to have taken his own life on Tuesday after allegations of inappropriate conduct were made against him, the subject of which he said, in a statement prior to his death, he did not know.
He had been sacked from the Cabinet and suspended by the Labour Party as a result of the allegations.
The Labour Party, and Welsh First Minister Carwyn Jones, have been criticised for the way the situation pertaining to Sargeant was handled, particularly after his family published correspondence between his legal representative and the party to illustrate concern over his treatment.
Mark Tami, the MP for Alyn and Deeside and a former Westminster colleague of Sargeant's, said there was an issue if MPs didn't know what they were supposed to defend.
He told Julia Hartley-Brewer: "I’ve known Carl for 16 years. Beneath the tough exterior, he was a big softie.
"These are hurtful, difficult issues to deal with and when you don’t know what they are, you don’t know what you’re defending. We need to look at how we do this.
"We need to have a process which is fair to everyone. It’s no good saying the procedures were followed.
"If the procedures were followed, then there’s something wrong with the procedures because someone died here."
