Varoufakis attended an event in London hosted by "The Guardian" on 23 October 2015, where he spoke about the UK's upcoming European Union membership referendum. He said that the UK should remain in the EU, but also campaign to democratise it: "My message is simple yet rich: those of us who disdain the democratic deficit in Brussels, those of us who detest the authoritarianism of a technocracy which is incompetent and contemptuous of democracy, those of us who are most critical of Europe have a moral duty to stay in Europe, fight for it, and democratise it." He would return to the UK, in May 2016, in the final stages of the campaigning to again urge a remain vote.
