On 23 June 2016, the United Kingdom voted to leave the European Union by 51.9% to 48.1%. In our post-referendum Brexit briefing, we summarised the required next steps, the five possible models that had been the subject of discussion leading up to the referendum and the legal implications of Brexit.
