Political positions of Boris Johnson

Boris Johnson has declared his position on many political issues through his public comments. Johnson's political positions have changed throughout his political career. His policies, views and voting record have been the subject of commentary during Johnson's tenure in various positions, including as Mayor of London from 2008 to 2016 and Prime Minister of the United Kingdom from 2019 to 2022.

Johnson is a supporter of unionism. He has sometimes been described as Eurosceptic, and advocated for a referendum on European Union membership for some time before the 2016 vote, during which he endorsed Vote Leave. Before and during his premiership, his views on Brexit included endorsing leaving the Single Market and leaving even without a deal. He opposed Theresa May's Chequers plan and Irish backstop, and as Prime Minister renegotiated the Brexit withdrawal agreement and replaced the latter with the Northern Ireland Protocol.

Johnson's views on the environment have changed; he wrote several climate skeptical columns in the 2010s but advocated for political action on climate change and renewable energy transition by the 2020s. In foreign policy, he was a transatlanticist, supported the Saudi Arabian–led intervention in Yemen and endorsed a more aggressive policy towards Russia, including by imposing sanctions on Russia, supporting Finland and Sweden's NATO membership bid, and supporting Ukraine during Russia's ongoing invasion, authorizing billions in foreign aid and weapons shipments to Ukraine. While Johnson initially wanted closer relations with China, he turned hawkish on the country by the end of his tenure, as he had established a citizenship pathway for emigres from Hong Kong and joined the AUKUS security pact.

Johnson has been described as an adherent of one-nation conservatism. Commentators have also likened Johnson's political ideology to liberalism and libertarianism, and in some cases Gaullism and Trumpism. Some of his views and political leanings have changed over time. On certain issues, he has been described as slightly more liberal than others in the Conservative Party.
