Chong Chieng Jen

Following incumbent Stamping MP Julian Tan Kok Ping's decision to retire from politics, Chong moved to contest the Stampin parliamentary seat against SUPP president Sim Kui Hian in the 14th Malaysian general election on 9 May 2018, which was seen as a 'grey' or unsafe seat following redelineation by the Election Commission of Malaysia (EC). His special assistant, Kelvin Yii Lee Wuen, contested for the Bandar Kuching seat. Chong went on to win with a majority vote of 14,221. Following the historic events of the 14th Malaysian general election which saw the first-ever change in the Government of Malaysia and end of six decades of National Front (BN) rule, on 2 July 2018, Chong was sworn-in as Deputy Minister of Domestic Trade and Consumer Affairs of Malaysia by the Yang di-Pertuan Agong (King of Malaysia).

On 7 May 2016, during the 11th Sarawak state election, Chong retained his Kota Sentosa state seat with a majority vote of 2,819 against Yap Yau Sin. On 12 November 2017, during the DAP Central Executive Committee (CEC) re-election, Chong was re-elected as one of the party's five national vice-chairperson.

On 17 December 2012, during the DAP 16th National Congress, Chong was among seven DAP leaders appointed to the party's Central Executive Committee (CEC). On 5 May 2013, he contested for the Bandar Kuching parliamentary seat for the final time in the 13th Malaysian general election and retained the seat with an even larger majority of 19,642 against SUPP's Tan Kai.

In the 11th Malaysian general election, Chong was elected as MP for Bandar Kuching with a 2,041 majority vote, and later, Sarawak state assemblyman for the newly created seat of Kota Sentosa in following the results of the 11th Sarawak state election.

Chong defended his parliamentary seat in the 12th Malaysian general election with an increased majority. In 2011, he once again, he defended his state seat, this time against Yap Chin Loi, with a majority vote of 4,824.

Chong first took part in the 10th Malaysian general election, contesting for the Bandar Kuching parliamentary seat as a DAP candidate but lost to Sarawak United People's Party (SUPP) candidate, Song Swee Guan. In the following 10th Sarawak state election, he contested for the Padungan state seat, eventually losing out to Lily Yong Lee Lee, also a SUPP candidate.
