The House of Commons Library has published a lengthy document considering the impact of Brexit in a number of policy areas, including consumer protection and public procurement. Various outcomes are discussed, depending on the results of the Brexit negotiations, in particular whether the UK stays in the European Economic Area, and how the government fills any policy gaps left by withdrawal. Whilst the paper does not deal with commercial issues in detail, the introductory sections provide a useful background and guide to likely Brexit options for the government to consider.
