Lim Kit Siang
In 2008, after winning 12th general election, Lim Kit Siang issued an instruction for all DAP representatives to boycott from the swearing-in ceremony for Perak Menteri Besar, claiming that there was no DAP mandate for PAS Menteri Besar in Perak. This caused the Perak MB swearing-in ceremony to be cancelled and only took place after Lim Kit Siang apologised and retracted his instruction.
