Sarawak Progressive Democractic Party (SPDP) president William Mawan Ikom has quit the party.

He quit this afternoon along with SUPP senior leader Wong Soon Koh, with both joining newly-formed BN-friendly party Parti Tenaga Rakyat Sarawak (Teras).

Both were embroiled in party disputes before announcing their resignations at the state legislative assembly building in Kuching this afternoon.
