 John Major supported a second referendum over Brexit, stating that the leave campaign put out a "fantasy case" during the referendum campaign, adding that to describe a second vote as undemocratic was "a rather curious proposition" and that he could see no "intellectual argument" against redoing the ballot.Major feared Brexit will make the UK poorer and could endanger the peace settlement in Northern Ireland.On 30 August 2019, it was announced that Major intended to join a court case by Gina Miller against the proroguing of Parliament by the Prime Minister, Boris Johnson.
