Wan Azizah Wan Ismail
Federal parliamentary opposition leader Anwar Ibrahim had confirmed to stand as the Pakatan Rakyat candidate in the by-election. However, due to the unusually swift conviction by the Court of Appeal in his sodomy case, his wife Wan Azizah Wan Ismail replaced him as the PR candidate. Barisan Nasional, which forms the opposition in the Selangor Assembly, named MCA vice president and former Petaling Jaya Utara MP Chew Mei Fun as their candidate.
