The rules that dictate how Senedd members should behave prevent politicians from defending themselves against unfounded allegations, according to a senior Plaid Cymru Senedd member.
Siân Gwenllian was found to have broken the code of conduct after she passed on parts of a confidential letter which showed that a complaint against her had been dismissed.
The MS for Arfon told the Senedd that Welsh Parliament politicians have "no right" to defend their reputations against complaints about their behaviour by sharing "relevant information".
The chair of the standards committee, Hannah Blythyn, said the committee was committed to helping to strengthening processes in place.
In a report published last week, the committee recommended that no action be taken against the Plaid Cymru politician for the code of conduct breach.
