The Channel Islands Brussels Office (CIBO) is the joint office of the Governments of Guernsey and Jersey that opened in 2011 to promote the interests of the Channel Islands in Europe and to represent the Channel Islands to the EU institutions.

The Channel Islands (“the Islands”) comprise the Bailiwicks of Guernsey and Jersey. 


They are autonomous British Crown Dependencies with a direct allegiance to the British Crown which goes back over 800 years. They are not part of the UK, are not represented in the UK (Westminster) Parliament and receive no financial subsidy from the UK government.

They have their own parliaments and legal systems, and full fiscal autonomy. 

The EU-UK Trade & Cooperation Agreement (TCA) applies to the Islands to a more limited extent than to the UK. 

CIBO has 3 permanent members of staff: Rebecca Millar (Director), Kerry O’Donoghue (Economic Affairs Attaché) and Senthia De Buyst (Operations Manager and Policy Assistant). 

CIBO also has regular short-term secondees from the Jersey and Guernsey public administrations, and interns. CIBO’s offices are on Rond-Point Schuman in the heart of the district in Brussels where the European institutions are located.

Guernsey and Jersey are not sovereign states, but they are not and have never been part of the UK, a British colony or a dependent territory.
