Bersih movement in Malaysia

My KL friend wore a yellow tie. He said that it is the symbol of the Bersih movement. This movement is a NGO and is led by professionals, and not by the political parties. The members of the movement want to see fair elections and are quite tied of the manipulation by the ruling party. The recent demonstration was for the people to voice their unhappiness and to send a memorandum to the Agong (King) to convey the message to the government on the need to change some of the rules to give all political parties a more level playing field to contest in the coming general election.
