In the 2016 United Kingdom European Union membership referendum, 51.9% voted in favour of leaving the EU, which meant that the Britain Stronger in Europe campaign was unsuccessful in achieving its main goal.

Following the referendum, many of the individuals involved such as Peter Mandelson and Roland Rudd would go on to form the Open Britain campaign group. On 6 September 2016 Britain Stronger in Europe officially changed its name on Companies House to Open Britain.[5] On 15 April 2018,[6] Open Britain launched the People's Vote, the campaign for a second EU Referendum.
