Description
The 2016 Brexit vote in the United Kingdom ushered in a period of political chaos, culminating in the collapse of Theresa May’s government and the rise of the pro-Brexit faction within the Conservative Party under Boris Johnson. Despite early indications that foreign and security policy would be an important area of stability post-Brexit, the Johnson government oversaw efforts to shift Britain’s international role in important ways, including in overseas development aid, the strategic relationship with the EU, in the signing of new trade and security agreements, and in changes to the UK’s force posture. None of these changes were inherent in the Brexit agenda, but may rather be traced back to the ideological concerns of the Johnson government – especially its preoccupation with sovereignty – and to the significant domestic changes which occurred during the course of the EU-UK withdrawal negotiations. Drawing on over 20 interviews with policymakers and senior think-tank officials, this paper demonstrates the impact the growth of conservative ideology has had on UK foreign policy since the 2016 vote. In doing so, it contributes to our understanding of the link between party ideology and foreign policy and the conditions under which party positions ‘matter’ for external policies.
