The former Segamat MP reportedly breathed his last in his sleep about 8pm last night at his residence in Seksyen 16, Petaling Jaya, surrounded by family members.
Subramaniam, who has been bedridden since suffering a stroke on Nov 11, 2011, is survived his wife Tina Subramaniam, 70, and three children.
The funeral will reportedly be held on Thursday.
Subramaniam's political career began at the age of 30 when he was handpicked by the then MIC president V Manickavasagam, to be fielded in the Damansara seat in the 1974 general election.
He failed to retain the parliamentary seat in the 1978 election, following which he was moved to the Segamat parliamentary constituency in the 1982 polls. He won the seat and held it until 2004, when he was dropped by the then MIC president Samy Vellu.
Subramaniam was the longest serving MIC deputy president - a post he held from 1979 to 2006. During the period, he also served in various government positions in different ministries.
Meanwhile, Prime Minister Ismail Sabri Yaakob has extended his condolences to the family of the deceased.
