According to nearly complete returns reported by Swedish television, the Social Democrats won 44.9% of the votes and 159 seats in the Parliament. With the help of the Communists, who vote with the Social Democrats and won 19 seats, the 58-year-old [Olof Palme] will have 178 seats, a majority of seven in the 349-seat Parliament.
The opposition parties have thus forced Palme to depend more on his Communist allies. In the past Parliament, Palme's Social Democrats had enough seats to outvote the parties on its right even if the Communists abstained, but that will not be true in the new Parliament.
The situation, however, will not be a new one for Palme. Swedish elections are traditionally close, and the Social Democrats have had to depend on the Communists for their majority before.
