An anti-corruption movement has said new laws being drawn up to protect whistleblowers will not deter certain employers from targeting those who reveal malpractice.

The Protected Disclosures Bill aims to protect workers who reveal wrongdoing by giving them more compensation and immunity from prosecution.

Workers who are victimised for whistleblowing could receive up to five years remuneration in compensation under the new legislation.

But, speaking on RTÉ's Morning Ireland, Transparency International Ireland Chief Executive John Devitt said he thinks the new legislation will not stop "unscrupulous" employers from targeting whistleblowers.

He said: "I don't think it's going to stop any unscrupulous employers shooting the messenger ... there are plenty of examples where whistleblower legislation is already in place but where unscrupulous employers are targeting people who speak out and share information that either the authorities or businesses don't want out there."

However, Mr Devitt said the new laws will still encourage more people to speak out against wrongdoing as it offers them a new "safety net".
