Sungkai assemblyman A Sivanesan said such calls would only push parties such as Kedah menteri besar Sanusi Nor to call for Penang’s return to Kedah.

“So many other matters can be raised for the rakyat’s benefit. Such a proposal should not have been raised.

“This is similar to the call made by Perikatan Nasional leaders for Penang to be returned to Kedah. I ask MPs to be careful when you make such proposals or statements in the future,” he was quoted by Malaysiakini as saying.

PKR’s Petaling Jaya MP Lee Chean Chung recently called for Kuala Lumpur to be returned to Selangor to create a “mega metropolis” and improve living conditions in the Klang Valley.

Kuala Lumpur, Selangor’s former state capital, was given up in 1974 to create a federal territory.

Ever since he took over as Kedah menteri besar three years ago, Sanusi has insisted that Penang is on lease from Kedah.

He went on to say the historical narrative on Penang’s ownership ought to be fixed to restore Kedah’s rights.

Prime Minister Anwar Ibrahim has dismissed Sanusi’s claims, saying the menteri besar does not understand the country’s laws and constitution.
