Speaking to FMT, he said PAS President Abdul Hadi Awang and his Ikatan counterpart, Abdul Kadir Sheikh Fadzir, were such contrasting personalities that it would be “extraordinary” to see them making a success of the collaboration.

“It will take a long time for Kadir to make Hadi be like Kadir and it will take Hadi a long time to make Kadir be like Hadi,” he said.

“It’s a contradictory situation. Both are good people; so it will be interesting to see how they work together. It’s just like oil and water mixing.”

He warned those thinking of joining Hadi and Kadir that “the boat could capsize.”

Sanusi is a former menteri besar of Kedah.

The PAS-Ikatan alliance has not been well received by opposition politicians, with Parti Amanah Negara’s Hanipa Maidin describing it as “pointless” and DAP’s Lim Kit Siang referring to the two parties as “zeroes.”

MIC President S Subramaniam has also dismissed it as inconsequential.

PAS and Ikatan leaders have said the alliance would be an issue-based pressure group that would engage the government in dialogue rather than oppose it for the sake of doing so.
