Lim Kit Siang (Chinese: 林吉祥; pinyin: Lín Jíxiáng; Pe̍h-ōe-jī: Lîm Kiat-siâng; born 20 February 1941) is a retired Malaysian politician.

Lim was admitted to the English College Johore Bahru to continue his sixth form studies but dropped out after two months to marry his wife, Neo Yok Tee, at the age of 19.

Lim was named by the government as a suspected instigator arrested under the Internal Security Act, which allowed for indefinite detainment.

He was denied access to a lawyer or his family for the first of two months he was held in solitary confinement, and Lim claimed the authorities tried to break him down psychologically.

[clarification needed] The Prime Minister of Malaysia, Abdul Razak Hussein, moved a motion in Parliament to prevent Lim from serving as an MP, granting him instead a period of time to request a royal pardon from the Yang di-Pertuan Agong (King).

[8] In 1979, he was convicted of five charges under the Official Secrets Act for exposing an arms deal between the Malaysian government and a Swiss company.

Lim was then elected to an advisory role as the leader of a newly created body called the "Policy and Strategic Planning Commission".

Lim contested and won in the constituency of Gelang Patah against Barisan Nasional heavyweight and former Menteri Besar of Johor Abdul Ghani Othman in the 2013 general election.
