The Communist-dominated Parliament, rejecting the recommendation of President Lech Walesa, overwhelmingly decided Saturday to delay new parliamentary elections until autumn.

The Sejm, or lower house, voted 314-18 with 40 abstentions to dissolve itself and the Senate not later than Oct. 30. The measure also said a new electoral law should be approved before that time.Before approving the legislation extending the life of a Parliament that was seated as a result of June 1989 elections in which 65 percent of the seats were reserved for the Communists and their allies, the deputies rejected, 92-231 with 43 abstentions, a proposal by the Solidarity caucus to hold elections May 26.
