The Election Results Tables are divided into three separate sections showing, respectively, the results from 1885 - 1950, 1950 - 1983 and 1983 - date.
These tables show the party winning each constituency at every General Election since 1885. (By-elections and changes of party allegiance not at a General Election are ignored.) Four colours are used to denote the parties and their allies, with the totals for each colour group being shown in the table:
Blue - Conservative, Coalition Conservative (1918), Liberal Unionist (1886 - 1910), National (1945), National Liberal (1931 & 1935 only), National Labour (1931 & 1935), National Liberal & Conservative (1950 - 1966);
Red - Labour, Coalition Labour (1918). (No attempt is made to distinguish Labour & Co-operative from Labour, although the sole General Election winner standing as just Co-operative (Kettering 1918) is shown as White.)
Yellow - Liberal, Coalition Liberal (1918), Liberal Democrat, SDP (1983 & 1987 only), Liberal/Labour.
Green - (only outside England) Scottish National Party, Plaid Cymru, Irish Nationalist.
White - any other party and independents. (The Speaker is shown in the same colour as the last time that he or she was elected under a party label.)
