Plaid Cymru's Parliamentary leader, Elfyn Llwyd MP, has welcomed comments made by Keith Towler, the children's commissioner for Wales, that legislation is needed to tackle cyber-bullying.
Mr Llwyd, who called for robust action to tackle the huge rise in cyber-crimes during his speech to the Plaid Cymru annual conference over the weekend, said that all individuals should have the right to feel safe online and that it was particularly important to protect young people.
He added his disappointment that the Welsh Government failed to see the merit in legislating against such a serious crime.
Mr Llwyd said:
"In my address to conference over the weekend, I called for the establishment of a cross-party commission to explore how best to tackle the huge rise in cyber-crimes.
"I am therefore very pleased to learn that the children's commissioner for Wales shares my wish to see legislation introduced to tackle these terrible crimes which often target impressionable young people.
"Having chaired the independent parliamentary inquiry into reforming the stalking law last year, I have now set up an All-Party Parliamentary Group on Stalking that will also be looking at tackling cyber-crimes including bullying, trolling and online stalking.
"It is, however, disappointing to learn that the Welsh Government has seemingly dismissed the commissioner's call, stating instead that it is better to "develop respectful relationships than criminalise bullying".
"Bullying has driven many young people to depression and even suicide as recent tragic cases have shown - if this doesn't warrant robust legislation then I struggle to think what does.
"I will be writing to the commissioner to request a meeting with a view to updating him on the APPG's progress on tackling cyber-crimes and hopefully discuss what steps can be taken to protect young people in Wales from these heinous offences."
