If Datuk Saifuddin Abdullah feels that PAS is good, then he should just join the party, Gerakan Youth chief Tan Keng Liang says.

Describing the former Temerloh MP's statement as "contradicting", Tan said Saifuddin has to make up his mind when he said PAS was not a problem.

Tan said in politics, one either agrees or disagrees with a certain stand.

"For me, my stand is clear. I don't think we can have them (PAS) in Putrajaya. After seeing how they operate in Kedah and Kelantan, I don't think they are suitable.

"Maybe that's why the people in Kedah rejected them," said Tan when contacted by Astro AWANI.

The 37-year-old outspoken youth leader today lashed out at PAS on Twitter, claiming that the Islamic party had been forcing their will against people.

"I don't think moderation comes with PAS. Even DAP cannot accept PAS nowadays... and even PKR," said Tan, citing the 'disagreement' between PAS and PKR over the recent Selangor MB issue as example.

Meanwhile, Saifuddin defended his statement, saying that one party cannot view the other party as a problem just because the two have been competing in elections.

"For me, PAS' existence is not an issue as they have been participating in the democratic process just like Barisan National.

"Therefore, in politics we fight but we cannot view them as a problem," the UMNO man told Astro AWANI.

Asked on why BN needs to continue to fight PAS despite some PAS members being open to moderation, Saifuddin said it was because the two have opposing policies and views.

He said when election comes, they still have to compete on who has the better policies.

Nevertheless, the Global Movement of Moderates Foundation (GMMF) CEO said opposing thoughts and policies between parties did not prevent them from holding meetings and discussions.

"So the existence of PAS, for me, is not a problem even to BN because we always continue to compete," he said.

Earlier, Tan's labelling of PAS being a 'problem' had received objection from Saifuddin on Twitter.

Saifuddin said although he had vowed to continue to fight PAS, he didn't agree when Tan said the party was a problem.
