The 1917 Dundee by-election was a parliamentary by-election for the British House of Commons constituency of Dundee in the county of Angus held on 30 July 1917. Vacancy The by-election was caused by the appointment of one of the two sitting MPs for the constituency, Winston Churchill, as Minister of Munitions. Under the Parliamentary rules applying at the time, members appointed to ministerial posts had to resign their seats and fight a by-election. At that time Dundee was represented by Churchill as a Liberal with Alexander Wilkie holding the other seat for Labour. Churchill’s return to government Churchill's appointment to the government represented a political comeback, one of many in his career. Closely associated with the military fiasco of the Gallipoli landings on the Dardanelles and the dreadful loss of life of Allied personnel, Churchill had been replaced as First Lord of the Admiralty and given a lesser appointment as Chancellor of the Duchy of Lancaster This was apparently one of the Conservative demands for joining the first Coalition government of the First World War under prime minister H H Asquith and may have had as much to do with settling old scores against their former rising star as their reservations about Churchill's skills as a military strategist. In November 1915 Churchill resigned from the government and went to the Western Front on active service as a battalion commander. In December 1916 David Lloyd George, Churchill's former close colleague in Asquith's radical reforming administration between 1908 and 1914, became prime minister. By July 1917, now secure in his position vis-a-vis his Conservative coalition partners, Lloyd George was ready to recall Churchill to the Cabinet, perhaps to strengthen its Liberal composition even further. A report into the Dardanelles disaster published in March 1917 had concluded that Churchill was neither solely nor principally responsible and Churchill was beginning to re-establish himself as an effective Westminster performer. One source even suggests that Lloyd George feared Churchill could emerge as a new leader of the opposition if the war continued to go badly. But Lloyd George clearly wanted his talented old ally as a support in difficult times and despite widespread criticism of Churchill's recall Lloyd George announced Churchill's appointment as Minister of Munitions on 18 July.
