On 22nd February 2016, David Cameron told the British people they faced the most important decision of their lifetimes – whether to leave or remain in the European Union. The government recommended remaining in the EU, but 85% of the public wanted more information. So we sent a leaflet to 27 million households at a cost of £9.3 million explaining the benefits of EU membership and risks of leaving. Our leaflet sparked widespread discussion. Boris Johnson called it "Project Fear" and Nigel Farage said it was "full of lies." And the rest is history.
