Former Felda Global Ventures Holdings Berhad (FGV) chairperson Isa Samad and his wife Bibi Sharliza Mohd Khalid have been summoned by the Malaysian Anti-Corruption Commission (MACC).

The couple is expected to have their statements recorded at the MACC headquarters in Putrajaya tomorrow, according to New Straits Times.

The move to question Isa and his wife follows his resignation as FGV chairperson yesterday.

Sulaiman Mahbob, the chairperson of Telekom Malaysia Berhad, stepped in as acting chairperson.

Isa also resigned as the chairperson of MSM Holdings, the company which manages FGV's sugar business and is one of two companies with a duopoly of the sugar industry.

He had cited personal reasons for his departure but the move was widely seen as a resolution plan put in place by Prime Minister Najib Abdul Razak following the completion of a fact-finding mission by former minister Idris Jala.

Najib had pledged to resolve the FGV crisis before Hari Raya Aidilfitri, which is expected to fall on this Sunday.

Immediately after Isa's resignation, Najib announced that he would be appointed as the acting chairperson of the Land Public Transport Commission (Spad).

The FGV crisis was sparked after the company's board, led by Isa, moved to suspend FGV chief executive officer (CEO) Zakaria Arshad and three other executives.

Zakaria claimed he had tried to stop "ridiculous investments" advocated by the board which had run up to hundreds of millions of ringgit, a claim which FGV denied.

The FGV board accused Zakaria of violating corporate governance rules.

The MACC on June 7 questioned Zakaria and followed up with a raid on FGV's office a day later.

Following Idris' report on the crisis, Najib said internal probe against Zakaria and three other executives will proceed where they will be allowed to defend themselves.
