After the Great War, the Silver Shirts, under Oswald Mosley, seemed to be in position to overtake the Conservative Party as Britain's rightist party. The Conservatives outflanked the Silver Shirts by shifting farther to the right under the leadership of Winston Churchill. In the 1930s, the Conservatives won control of the Government by entering into a coalition with the Silver Shirts. Churchill became Prime Minister and Mosley became Chancellor of the Exchequer.
