Prime Minister Najib Razak hopes Tun Dr Mahathir Mohamad will re-consider his decision to step down as Petronas adviser.

Najib said this was because the government felt that the former prime minister was still able to contribute to Petronas' development and success.

"In respecting Tun's decision, which was made on doctor's advice, I hope Tun can reconsider the decision.

"The government welcomes Tun to continue to serve as Petronas adviser," he told reporters after a meeting, which lasted for nearly an hour, with Hamas leader Khalid Meshaal at the Putra World Trade Centre in Kuala Lumpur today.

Najib said he had received the resignation letter from Dr Mahathir.

Mahathir had confirmed his resignation as Petronas adviser, effective Dec 1, yesterday, due to age and health factors.

He was appointed Petronas adviser after his retirement as prime minister in 2003.
