Joseph Edmund Johnson (born 23 December 1971) is a British politician serving as the Member of Parliament (MP) for Orpington since 2010. He is a member of the Conservative Party. His brother, Boris Johnson, is the leader of the party and Prime Minister. Johnson was appointed Director of the Number 10 Policy Unit in 2013 by Prime Minister David Cameron. He became Minister of State for the Cabinet Office in 2014 and Minister of State for Universities, Science, Research and Innovation in 2015. Following the January 2018 cabinet reshuffle, Johnson served as Minister of State for Transport and Minister for London; he resigned in November the same year, citing the failure of the Brexit negotiations to achieve what had been promised by the Vote Leave campaign and his wish to campaign for a new EU referendum.
