By Alvin Shuster Special to The New York Times
Swedish Soc Dem party, in power for 41 yrs, apparently wins narrow victory on Sept 17 over non-Socialist coalition in closest election in modern Swedish history; Soc Dems and their tacit allies, Communist party, with 91% of votes counted by 4 AM, Sept 17, hold 2-seat margin in seesaw battle over 350 seats in Parliament; experts still do not rule out possibility of pol confusion with 175-to-175 seat deadlock when all votes are counted; Premier O Palme, if he retains power, will be more dependent on Communist support in single-chamber Parliament; Palme controlled 163 seats at onset of election, which, combined with 17 held by Communists, provided him with workable majority of 180 seats; election returns show that Soc Dems lost considerable ground with electorate; latest figures show that Soc Dems lost 7 seats--down to 156 seats--but were saved by strong showing of Communists, who gained 3 seats for total of 20; Soc Dems, still largest single party in Parliament, manage to win only about 43% of vote, 3d lowest total for party in 15 elections since it came to power in '32; Communists appear to gain about 7% for about 5.5% of total; challenge to Palme Govt came from coalition of 3 parties, which had agreed if victorious to form new Govt under T Falldin, leader of fast-growing Center party, a former Agrarian group that made large gains in election; Center party wins 25% of votes, gain of 5%, and Liberal party loses nearly 7%; Conservatives gain close to 3%; voter turnout is unusually high at about 90%; death of King Gustav VI Adolf cast shadow over voting with official declaration of mourning; new King Carl XVI Gustaf arrives back in Stockholm from Halsingborg, in southern Sweden, where King died; Carl Gustaf will be officially installed on Sept 19-there is no coronation in Sweden--and will speak to his 8-million subjects for 1st time as king; Gustav VI Adolf will be buried on Sept 25; pol analysts are unable to judge whether death of king had any impact on voting; illus of King Carl Gustaf XVI arrival in Stockholm
