 The sixth Knesset is notable for being the only one in which a party has ever held a majority of the seats by itself.By the end of the session, the merger of Mapam and Rafi into the Alignment left it with 63 seats (53% of the total).Although the party came close to equalling the feat in the 1969 elections, when it won 56 seats (which is still the best electoral performance on record), no party has managed it since.
