Article: Following the hardliners' takeover, the September 30, 1990 elections (runoffs on October 14) were characterized by intimidation; several Popular Front candidates were jailed, two were murdered, and unabashed ballot stuffing took place even in the presence of Western observers. The election results reflected the threatening environment; out of the 350 members, 280 were Communists, with only 45 opposition candidates from the Popular Front and other non-communist groups, who together formed a Democratic Bloc ("Dembloc"). In May 1990 Mutalibov was elected Chairman of the Supreme Soviet unopposed.

Question: How many members were from opposition parties?
45
