After leaving the Army, Evans Gordon returned to Britain and in 1900 was elected as Conservative Party MP for Stepney on an anti-alien platform. As a result of the pogroms in Eastern Europe, Jews were arriving in increasing numbers in Britain either to stay, or "en route" for America. Evans Gordon, as a 'restrictionist', was heavily and actively involved in the passing of the Aliens Act 1905, which sought to limit the number of people allowed to enter Britain, even temporarily. He held Stepney from 1900 to 1907.
