The process of leaving the EU presented the biggest set of decisions faced by the UK polity for decades. Given its prominence and importance, decision-making needed to satisfy two conditions. First, it should respect and respond to public opinion: both democratic principle and the need for public legitimacy demand this.
Second, the process should be carefully considered: the options and their implications for all parts of society should be clearly understood and priorities carefully weighed. The project was designed to advance these goals – and thereby to make a major and distinctive contribution to the Brexit process – by creating a Citizens’ Assembly on Brexit.
