Parti Pesaka Bumiputera Bersatu (PBB) – the biggest component of Sarawak's ruling coalition – will consult its partners on whether they are still part of BN.

Party president Abang Johari Abang Openg announced this after PBB's supreme council meeting today.

"No need to be in haste," he said when asked when the discussions will take place.

Sarawak BN suffered unprecedented losses in the May 9 elections for federal parliament. It won 19 seats of the 31 seats available, down from the 25 it held previously.

Now that BN is no longer the federal government, the coalition appears to have ceased to exist, while question marks remain on whether the same will happen in Sarawak.

Abang Johari said that the 13 PBB MPs will "work together" with the new federal government, but did not explicitly state whether they are supporting the new ruling coalition.

"We will work with the federal government, but we won't join Pakatan Harapan," he said.

He did say that the 13 PBB MPs will provide check and balance, and "relentlessly" act as the voice for Sarawak in Parliament.

"We believe that the current government will appreciate fresh, fair and balanced intellectual discourses.

"We will fight for Sarawak first, of course," he said.

On federal government funding for the state, Abang Johari stated that Putrajaya has obligations to the state under the Federal Constitution.

At this point, it is unclear if PBB now viewed itself as an opposition party in Parliament or otherwise.
