This thesaurus is a collection of ECON related articles, papers and studies on the possible withdrawal of the UK from the EU. Recent literature from various sources is categorised, chronologically listed – while keeping the content of previous editions - and briefly summarised. To facilitate the use of this tool and to allow an easy access, certain documents may appear in more than one category. The thesaurus is non-exhaustive and may be updated. This document was provided by Policy Department A at the request of the ECON Committee.
