The dataset groups candidates into five party families: Conservative (including Ulster Unionists before February 1974), the Liberal family (Liberal, SDP–Liberal Alliance, Liberal Democrats), Labour, SNP and Plaid Cymru, and all others combined. “Most votes” marks the family with the largest vote in each constituency, not necessarily the seat's winner: the Other column aggregates many parties.
