In terms of raw numbers (but not percentage), the NDP increased its popular vote in the 1975 election. However, its vote outside of the Vancouver area plummeted, costing it 20 seats and its majority. Barrett was personally defeated in the Coquitlam seat he had held since its creation in a 1965 redistribution, losing to Socred challenger George Herman Kerster by only 18 votes. In June 1976, he was returned to the legislature in a by-election in Vancouver East, after sitting NDP MLA Robert Arthur Williams stepped aside. He remained an MLA for that riding until 1984, continuing to lead the NDP against Bennett's Socreds in the 1979 and 1983 elections.
