Any decisions made by Pakatan Harapan to officially accept new coalition partners for the forthcoming 15th general election must be carefully deliberated to avoid a repeat of Bersatu's treachery, Anwar Ibrahim said.

In an interview with Malaysiakini, the Harapan chairperson said that aside from Muda, the coalition also received a letter from PSM, seeking to rekindle ties and explore possible election cooperation.

"I think we can continue to engage, since these parties' policies are quite close to Harapan.

"But I will leave it to the presidential council, and later on to have the committee deliberate in detail," the PKR president said yesterday, ahead of a meeting to be held this afternoon at the party's headquarters.
