A by-election was held for the Dewan Rakyat seat of Permatang Pauh on 7 May following the nomination day on 25 April 2015.[1] The seat fell vacant after member of parliament Anwar Ibrahim was disqualified from holding his seat after being found guilty of sodomy in a highly controversial trial.[2] Anwar Ibrahim was a member of the Parti Keadilan Rakyat and leader of the opposition alliance Pakatan Rakyat. In the 2013 general election, Anwar won the seat with a majority of 11,721 votes beating Mazlan Ismail of Barisan Nasional.[3]
The Permatang Pauh by-election was contested by 4 candidates, consisting of former opposition leader, Anwar's wife Wan Azizah Wan Ismail from PKR, UMNO's Suhaimi Sabudin, PRM's Azman Shah Othman and independent candidate Salleh Isahak.[4] There were reports saying that PRM has denied that Azman Shah Othman is a member of their party.[5] [6]
Several issues dominate the by-election campaign, with the recently introduced GST being the main issue.[7]
An UMNO branch in Permatang Pauh dissolved during the campaign period, citing neglect by party leadership.[8]
Wan Azizah retained the seat for PR with a majority of just below 9 thousand votes.[9] Mirroring the trend shown in the Rompin by-election two days before, turnout dropped by more than 10% in Permatang Pauh. The lower turnout also means while PKR's majority is lower, their share of popular vote is practically unchanged.[10]
