Nucleus is a British-European advocacy group, based in London, but with additional operations in Brussels.
Founded in 2010, Nucleus promotes a 'euro-realist' British approach to European political and business affairs. As well as regular bulletins, Nucleus produces commentaries, and hosts briefings, seminars, and networking events both in London and Brussels.
Nucleus is a partner in both the British Brussels Network, along with Business for New Europe, the British Chamber of Commerce in Belgium, and the Institute of Chartered Accountants in England and Wales,[1] and the pan-European EuropAssociation.[2]
