The former prime minister said Penang under Lim as chief minister had given up 2,337.5 hectares of state land, adding that this included lands for the purpose of the tunnels projects and the Penang Transport Master Plan where land reclamation rights were granted.

He was responding to a statement by Lim that Penang had successfully managed to reduce the state’s debt by 90%.

But Najib said it was the restructuring of water assets by the federal government that managed to reduce some RM655 million, or 95% of debt, for the Penang government.

Najib said Lim himself admitted to this in a statement issued in 2014 and which was still available online.

“Let Guan Eng expose Guan Eng,” said Najib, in the latest of a series of Facebook posts hitting out at Lim, who took over the finance portfolio he once held as prime minister.

“The Internet never forgets,” he said.

“Guan Eng should be aware that he is no longer an opposition politician but has a serious responsibility as the country’s finance minister. He should be more honest,” said Najib.

Najib had earlier claimed that Penang’s financial performance over the last 10 years of annual budget surpluses, reduction in state debts by 90% and increase in asset reserves by 140% was due to the state’s land sales.

But Lim shot back saying the state had only sold 43 hectares “or 34 times less than the 1,481 hectares of land sold by the previous BN government”.

“Despite Pakatan selling off less land, it still received more money than BN because land was sold by open tender instead of direct negotiations as by BN,” the DAP leader had said.
