Parti Keadilan Rakyat

Known also as People's Justice Party, the part is led by former Deputy Prime Minister Datuk Seri Anwar Ibrahim. It is a centrist political party formed in 2003 which was merged between the National Justice Party and the Malaysian People's Party.
The formation of the party was widely prompted after Anwar was sacked from his Deputy Prime Minister post and arrested. Many seen then that the PKR was created as a personal grudge held by Anwar against the government. PKR or Keadilan, which was led by his wife Dr Wan Azizah Wan Ismail could only win one seat during the elections, which gave the party the sole voice in the parliament.
PKR, however over the past few years and with the release of Anwar has since garnered very strong support and the last elections saw them rising among the single digit to 31 seats. The fact that the people were more vocal in supporting the PKR perhaps have much to do with the fact that the party is actively seeking social injustice and anti-corruption agenda. They have even voiced a need to abolish the New Economic Policy and that it should be replaced with a more non-ethnic approach. This was welcomed by many and hence their landslide victory over the BN candidates.
Many believed that Anwar's downfall as the Finance Minister was his series of economic reforms and his controversial proposals to amend the Anti Corruption Act which was then did not coincide with the then Prime Minister Tun Dr Mahathir Mohamad. This led to him being sacked and alleged charges of sexual misconduct as well as corruption.
He then moved onto his Reformasi movement, which was championed wholly by the Parti Keadilan Nasional, led by Dr Wan Azizah Wan Ismail, his wife. this effort was then taken on by other opposition parties like DAP, PAS and PRM which formed the Barisan Alternatif (Alternative Front) to prepare for the 1999 General Elections.
Disappointingly, the elections saw that the Barisan Alternatif losing out more seats than expected seeing that the BN government maintained their two-third majority to then form the federal government. One of the reasons why Keadilan lost badly in the 1999 general elections was as believed by many because the party's leaders like Vice-President Tian Chua, Youth leader Mohd Ezam Mohd Nor, Mohamed Azmin Ali , Fairus Izuddin and Dr Badrul Amin Baharun; were all under arrest and could not contest in the elections.
Later on, the Keadilan merged with the Parti Rakyat Malaysia and was then renamed as Parti Keadilan Rakyat in August 2003. In 2004, Anwar was freed and his charges were overturned and in 2005, the second national congress was held where they passed the New Economic Agenda which are created to replace the New Economic Policy.
PKR was later joined by Khalid Ibrahim, the former CEO of Guthrie and Permodalan Nasional Berhad where he assume the Treasurer Post, KS Nallakarupan and Jeffrey Kitingan.
PKR's breakthrough came in the 2008 elections where they won 31 seats together with DAP and PAS where together would hold 82 Parliamentary seats. This would be a strong voice as compared to BN's 140 seats. This would subsequently deny the BN government the two third majority in making any constitutional change.
The PKR too has been successful in the state level where they came away with victories that secured 5 states onto the loose coalition of DAP, PAS and Keadilan.
After the elections, Anwar returned to politics after his ban from public office expired. It is widely believed that the reason opposition won so well in the elections were largely contributed by the fact that Anwar was the leader of the party, and keeping in view that he will be returning soon, many put their faith in him, standing behind the party.
