Our SW1 insurgency was bolstered by the People’s Pledge, a cross-party campaign for a referendum, launched in 2011 by Daniel Hodson, John Mills, Mark Seddon, Dan Hannan, myself and others. It effectively pressured MPs in marginal seats by organising local referendums, pushing them to support a national vote. I saw its impact firsthand at a drinks party in David Cameron’s Downing Street flat, where an irate MP confronted me about the campaign’s activity in her constituency. My suggestion that she sign the pledge sparked a scene. (Ironically, this now-former MP later framed her parliamentary legacy as helping secure Brexit, another case of selective memory.) In a move that would prove significant in the long run, Boris Johnson, then the London Mayor, had signed the People’s Pledge at one of our street stalls in Romford. We had not only mainstreamed the idea of a referendum, but had been able to do so because we had taken control of the Eurosceptic movement inside Westminster. Once Cameron had conceded holding a referendum, it was what was happening with Euroscepticism outside Westminster that became of greater concern.
