Identify this political person: Father name is Marudhur gopalamenon. Born in Kandy, Srilanka. Script for his first successful film is written by his political arch-rival!! His party won all the elections til his death !

M.G. Ramachandran (MGR) fits all the clues: his father was Marudhur Gopalamenon, he was born in Kandy (Sri Lanka), and his first successful film's script was written by M. Karunanidhi, who became his political arch-rival. His party (AIADMK) won every election until his death in 1987. NTR, Jyoti Basu, and Shivaji Ganesan don't match these details.
