ABSTRACT
The UK has frequently indicated that Brexit should not lead to a complete detachment from the EU’s foreign, security and defence policy, but that in this area EU membership should be replaced by a new security partnership. The present chapter aims to map legal institutional obstacles and possibilities for the UK to continue participating in CFSP by analysing both the Withdrawal Agreement and, in particular, the existing rules on participation of third states in the CFSP and CSDP framework. In doing so it draws on current examples of third state participation in EU foreign and security policy.
