PASIR GUDANG (THE STAR/ASIA NEWS NETWORK) - Politicians who have strayed should return to the right path, urged Malaysia's former prime minister Mahathir Mohamad.

He said some leaders had forgotten their duty to the people who voted for them as their representatives to protect their rights.

"Come back to the right path. You are lost," he told a large crowd at the Bicara Negarawan session held at Pasir Gudang Stadium here on Saturday.

"Our country's future has all the while been bright, but not anymore," he said.

Dr Mahathir also said he was still undecided on whether to attend a mass rally in Kuala Lumpur organised by electoral reform group Bersih demanding the resignation of Prime Minister Najib Razak.

"I'm still thinking," he said in response to a question.

Dr Mahathir has been one of the strongest critics of Mr Najib who is facing allegations of illegal transfers of funds into his personal bank account.

The former leader has repeatedly called on Mr Najib to relinquish his post. But the latter has insisted that he did not take any state funds for personal gains.
