Dr Russell Foster, senior lecturer in British and international politics, said: “Foreign policy and security are rarely vote-changing issues in general elections, particularly since the end of the Cold War and the subsequent 'peace dividend'. This has changed in 2024. Following Brexit the UK's foreign relations and reputation have been severely tarnished, with Britain trying - mostly unsuccessfully - to balance a relationship with the EU alongside aspirations of 'Global Britain'. At the same time, the global security situation has radically changed since February 2022. The Conservatives, until now seen as the party of defence and security, are largely not trusted with Britain's armed forces and foreign policy. Labour, following the disastrous Corbyn experiment, are struggling to present themselves as dedicated to national security and the rules-based Western order.
“Whoever wins an increasingly toxic election faces the challenge of rebuilding the UK's armed forces following 14 years of austerity and with limited funds, and establishing the UK's relationship with NATO, the EU, and the new European Political Community, alongside rebuilding Britain's international reputation as a reliable foreign policy actor. This will not be an easy task, as foreign policy is a highly contested and emotional issue for an angry electorate. Politicians across the spectrum speak of a 'new 1930s' and a 'pre-war era' for Britain, and for the first time since the end of the Cold War, parties' stances on foreign relations may prove the determining factor of the general election.”
