Jean-Baptiste Lemoyne (; born 15 September 1977) is a French politician of La République En Marche! (LREM) who served as Secretary of State at the Minister for Europe and Foreign Affairs in the governments of successive Prime Ministers ÃÂdouard Philippe and Jean Castex from 2019 to 2022.
Lemoyne was born on 15 September 1977 in Bourg-la-Reine, France.
In June 2002 he took one of his first political positions, becoming a technical advisor to Secretary of State for Relations with Parliament, Jean-François Copé. Two years later, in March 2004, when Copé became Minister delegated to the Interior and the government's spokesman Lemoyne followed as a technical advisor to him. In May 2005 he was appointed to the cabinet as a technical advisor of him again when he became Minister delegate for the Budget and State Reform alongside still being the government's spokesman. After the presidential and legislative elections of 2007, Lemoyne became deputy chair of the UMP parliamentary group at the National Assembly. He held this position until 2014, under successive chairmen Jean-François Copé (2007-2010) and Christian Jacob (2010-2014).
He was a notable opponent of the Law 2013-404, which granted same-sex couples the rights to same-sex marriage and for same-sex adoption. He first accused on Twitter of the National Assembly gagging right-wing deputies, and stated on Radio Fréquence Gaie he was going to help in the fight against marriage for all after voting against it. He later held a rally in Yonne after the law passed.
When German Chancellor Angela Merkel called for European Union member states to give European Commissioner for Trade Cecilia Malmström a clear mandate for negotiations with the United States on metal tariffs in 2018, Lemoyne publicly opposed these plans.
