On 20 August 2018, in an on-stage book festival interview in Edinburgh, Varoufakis pressed Jeremy Corbyn, head of the British Labour Party, to "be a bit more ambitious" and become involved in the international progressive movement, saying "We need a progressive international". On 13 September, Varoufakis penned an op-ed piece in "The Guardian" about the need for an international progressive movement, alongside a similar piece by fellow progressive U.S. Senator Bernie Sanders. On 26 October in Rome, Varoufakis announced the Progressive International, which was described as a "common blueprint for an International New Deal, a progressive New Bretton Woods". The organization officially launched on 30 November in Sanders' home town of Burlington, Vermont.
