Close

Across his political career, he has served as Housing, Local Government and New Village Minister as well as the Senate President.

He is married to Toh Puan Helen Chen.

Michael Chen joined the Malaysian Chinese Association (MCA) in 1960. He was elected MP for the Damansara constituency in Selangor in the 1964 general elections. He was subsequently appointed as Parliamentary Secretary to the Deputy Prime Minister, Tun Abdul Razak Hussein in Tunku Abdul Rahman's third cabinet. However, Chen failed to retain his seat in the 1969 general elections. In 1972, Chen was elected MP of Ulu Selangor after the death of the incumbent MP Khaw Kai Boh. Chen was appointed as Minister with Special Functions in Abdul Razak's first cabinet.

In 1977, Chen objected to an attempt to replace the Deputy President of MCA Lee Siok Yew with Chong Hon Nyan, and managed to defeat Chong for the position. He moved to challenge Lee San Choon for the MCA presidency itself in 1979, but was defeated. He did not challenge for the MCA presidency in 1981 as some who might have supported him had been expelled from the party; later he led a group of his supporters out of MCA to join the Gerakan.^[2]

He contested the 1982 election under the Gerakan's banner and won Beruas seat. He was a member of the parliament until 1986. From 1997 until 2003, he served in the Dewan Negara.^[3] He was deputy president from 1997 to 2000, and president from 2000 to 2003.^[1]
