What happened?
On 23 June 2016 the UK voted to leave the European Union. The result went against the view of most MPs, about three-quarters of whom had backed Remain, and so became the clearest case of the people overriding the preference of their representatives.
The Leave campaign was also controversial. Its claim that the UK sent £350 million a week to the EU was criticised by the UK Statistics Authority, and the official Leave campaign was later fined for breaking electoral law.
- Leave won 17,410,742 votes (51.9%) and Remain 16,141,241 (48.1%), a margin of 1,269,501 votes, on a turnout of 72.2%.
- About three-quarters of MPs (74%) supported Remain during the campaign. The Constitution Unit puts the figure at around 75%.
- On 27 May 2016 the chair of the UK Statistics Authority, Sir Andrew Dilnot, said that using the gross figure in a way that implied it was the UK's net contribution was misleading and undermined trust in official statistics.
- On 17 July 2018 the Electoral Commission fined Vote Leave £61,000 and referred it to the police. It found that Vote Leave had exceeded its £7 million spending limit by almost £500,000, including more than £675,000 spent by BeLeave with AggregateIQ under a common plan with Vote Leave.
Why is it politically significant?
The referendum shows popular sovereignty in action: Parliament, which was mostly pro-Remain, accepted the result. It also raises questions about the quality of referendum campaigns, since voters made a historic decision during a campaign marked by disputed claims and, on the Leave side, unlawful overspending.

Alternative view
Referendums are legally advisory
Parliament remained legally sovereign: it chose to act on the result and passed legislation to trigger withdrawal.
Limits of the evidence
Overspending did not prove the result was changed
The Electoral Commission found breaches of spending rules, but that does not show the outcome would have been different without them.
