Perkasa president Ibrahim Ali has proposed a detention without trial law in dealing with grand corruption.

"This law will have the same mechanism as the Internal Security Act.

"This law will fight corruption and abuse of power. It will not only apply to political leaders but also senior government officials as well as those in government-linked companies," he told a press conference in Kuala Lumpur today.

Ibrahim suggested that the law allows detention without trial for up to two months for graft cases involving more than RM1 million.

He said the proposal will be made at Perkasa's annual general assembly this weekend and later submitted to the government.

The Internal Security Act 1960 allowed detention without trial for up to two years which could be renewed indefinitely by the home minister.

It was meant to deal with terrorism, subversive activities and public order but was abused for political purposes. The law was repealed in 2011.

On a separate matter, Ibrahim said Sungai Besar Umno chief Jamal Md Yunos, who leads the red-shirts movement, should not be likened to him.

"I don't put myself at the same level as him. He is different, I am a leader in my own way," Ibrahim said.

Jamal has vowed to confront the Bersih 5 rally this Saturday, raising concerns of a clash.

Ibrahim was asked if this was any different from Perkasa which had in the past threatened to take on Bersih.

The Perkasa leader said unlike Jamal, he did it the "proper" way.

"Bersih went ahead with their rally at that time and we didn't harass them.

"We backed out and let police deal with them," he said.

On another matter, Ibrahim, who was the former Pasir MAS MP, said he was interested in contesting in the next general election.

He likened himself to a "sexy divorcee" with many suitors interested in courting him to join their party.

"I admit there are many quarters courting me but I'm not interested in joining any political party as I want to consolidate Perkasa.

"What is certain is I will contest in the general election, but I do not know how and I can't reveal it now," he said.
