Romanian political analyst Silviu Brucan, known in the West as former Ambassador of communist Romania to the US and UN, died following a heart failure while hospitalized in Bucharest on Thursday night. Brucan, 90, had undergone a surgical intervention for heart affection earlier this month.

Brucan served as Ambassador of communist Romania to the US (1955) and the United Nations (1959-1962). He later turned against Communist Party leadership under ex-dictator Nicolae Ceausescu and was one of the signatories of a “Letter of six communist dignitaries”, a protest addressed to Ceausescu in 1989.

After the 1989 revolution he became a political analyst popularized in TV talk-shows.
