Isle of Ely was a county constituency represented in the House of Commons of the Parliament of the United Kingdom, centred on the Isle of Ely in Cambridgeshire. Until its abolition in 1983, it elected one Member of Parliament (MP) by the first past the post system of election. History The Isle had previously been represented by two members of the First and Second Protectorate Parliaments, between 1654 and 1658. The twentieth century constituency was created in 1918 and remained virtually unchanged until its abolition in 1983. The territory included in the new seat was similar to that previously constituting the Wisbech constituency (the north division of Cambridgeshire). That constituency was dominated by the Fens, a district of Liberal inclined smallholders. The towns in the Wisbech division, predominantly Conservative Wisbech and the more Liberal inclined March, tended to be outvoted by the rural areas. The small city of Ely had formerly been part of the Newmarket constituency (the east division of Cambridgeshire). Pelling suggests Ely was Conservative "because of the cathedral and its fairly substantial middle-class population". In 1918, the former Liberal MP for Wisbech, Colin Coote, was returned unopposed as a Coalition Liberal. In 1922 Coote contested the seat again, this time as a National Liberal candidate. A Labour candidate appeared for the first time. The anti-Conservative vote was badly split (National Liberal 27.7% and Labour 21.4%), so the Conservative soldier Lieutenant Colonel Norman Coates was easily elected. Coates retired and did not seek re-election in 1923. In 1923, the reunited Liberal Party nominated a member of the family of one of their richest members. Henry Mond was the son of the industrialist Alfred Mond (later the 1st Lord Melchett). He was able to squeeze the Labour vote down to 12.4%, which was sufficient for a narrow Liberal victory as part of the party's best election result after the First World War. In the 1924 general election, both the Conservative and Labour candidates increased their vote. Mond was defeated. The new MP was the Conservative, Sir Hugh Lucas-Tooth, Bt. Lucas-Tooth had a long political career, not leaving the House of Commons until 1970, but he only retained this seat for one Parliament until his defeat in 1929. The Monds had joined the Conservative Party in 1926 after a disagreement with Lloyd George's land policy. However another rich Liberal stood in this constituency in 1929, the flamboyant James de Rothschild.
