Relationship context
Overview
Gibraltar is a British Overseas Territory with substantial self-government under its 2006 constitution, while the United Kingdom retains responsibility for areas including defence and foreign affairs. Gibraltar’s government has worked with the UK through bilateral ministerial mechanisms, but sovereignty and the extent of Gibraltar’s autonomy remain sensitive issues. The relationship combines durable constitutional cooperation with recurring political friction.
Areas of tension
- Gibraltar’s sovereignty and the UK’s territorial claim
- The scope of Gibraltar’s self-government and the UK’s retained responsibilities
- Arrangements for Gibraltar’s relationship with the European Union
Key developments

Major uncertainties
