Foreign Minister Anifah Aman dismissed claims linking him to the high-profile graft case in Sabah as "preposterous and false".

He said this in reference to allegations that the director and deputy director of a utilities company arrested by the Malaysian Anti-Corruption Commission (MACC) were linked to Kimanis Umno, which Anifah heads.

MACC seized RM114.5 million, including RM53 million in cash, from the duo which was believed to have been corruptly obtained through their positions, where they oversaw RM3.3 billion in infrastructure projects.

"I refer to allegations being circulated that the recent arrests of two top officers of the Sabah Water Department and seizures of cash, jewellery and assets by MACC are related to Kimanis Umno and I as the Foreign Affairs Minister Malaysia.

"These allegations are preposterous and false.

"Kimanis Umno and I are not in any way involved or implicated in the case under investigation," Anifah said in a statement today.

He added that action would be taken against those who made the false allegations.

"We will not hesitate to take any legal action should these defamatory statements continue to be published," he said.

Anifah said the MACC should be allowed to do its job fairly and without interference.
