Britain Stronger in Europe

Britain Stronger in Europe (formally The In Campaign Limited) was an advocacy group which campaigned in favour of the United Kingdom's continued membership of the European Union in the 2016 British referendum. It was launched at the Old Truman Brewery in London on 12 October 2015, and declared as the official "Remain" campaign for the referendum by the Electoral Commission on 13 April 2016.

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. On 15 April 2018, Open Britain launched the People's Vote, the campaign for a second EU Referendum.
