Past prime ministers implicated in land swap deals involving the Defence Ministry will be probed, Prime Minister Dr Mahathir Mohamad pledged today.

"The police will investigate the prime minister as well, no one is above the law," he told a press conference after chairing a special cabinet meeting on anti-corruption.

The land swap deal report tabled in Dewan Negara on May 9 found that "political considerations outweighing government interests" were present in the first land swap deal made in 1997, during Mahathir's previous tenure.

The 59-page report by the Governance, Procurement and Finance Investigating Committee pointed to the involvement of two former prime ministers and defence ministers in 13 out of 16 land swap deals.

At his press conference today, Mahathir did not refer to any former prime ministers by name.
