One of the hard-line organizations implicated by Al Jazeera in a movement to overthrow President Susilo Bambang Yudhoyono and install an Islamic-based government says the allegations against it are false.

"That is misleading, not true," Muhammad Al Khaththath, secretary general of the Islamic People's Forum (FUI), told Tempointeraktif.com on Wednesday.

Khaththath told Al Jazeera that he had met with retired generals who wanted to overthrow the government and admitted that he was one of those who had drafted the proposed cabinet.

It names Islamic Defenders Front (FPI) chairman Habib Riziq as president and well-known radical Abu Jibril, a senior member of the Indonesian Mujahidin Council (MMI), as vice president.

Khaththath, as quoted by Okezone on Wednesday, said the Islamic cabinet was prepared during the Bank Century crisis in 2010 to anticipate "the possibility of a power vacuum."

Retired Army Chief Gen. Tyasno Sudarto was also named to a senior position in the cabinet.

The Al Jazeera report alleged that "senior retired generals" were supporting the FPI and other hard-line groups to incite religious violence as part of a wider attempt to oust Yudhoyono.

It quoted Chep Hernawan, leader of the Islamic Reform Movement (Garis), as saying the generals were using the groups in their efforts to topple Yudhoyono because they feel he is "too weak and too reformist."

The report concluded that though there was little likelihood of this occurring, Indonesia's high-profile battle against religious extremism "seems hard to win."
