While PAS may seem eager to help Umno campaign during by-elections, it does not appear keen on forming unity governments in east coast states, according to Terengganu Amanah chief Raja Kamarul Bahrin Raja Ahmad.
In a statement today, Raja Bahrin described PAS as being "two-faced," and asked if it had trouble accepting Umno in Terengganu and Kelantan because of "old wounds."
"Why is PAS showing two faces? They are friendly with Umno on the west coast, but behave differently in Terengganu and Kelantan," asked the former PAS member.
Raja Bahrin said PAS leaders owe the party grassroots an explanation, since they had made sacrifices on Umno's behalf in recent by-election campaigns.
Following the first technical committee meeting between Umno and PAS last week, acting Umno president Mohamad Hasan had publicly mooted unity governments in states where both parties are governing.
Umno is heading the governments of Perlis and Pahang, while PAS controls Kelantan and Terengganu.
However, PAS vice-president Iskandar Abdul Samad's immediate reaction had been that it was too early to make such a commitment, as co-operation with Umno was limited to by-election campaigns at this point.
