Change UK was a centrist political party founded by disgruntled members of parliament from the Labour and Conservative parties which sought to achieve a second Brexit referendum. The party's final leader, Anna Soubry, disbanded the party a week after the 2019 UK general election, in which the party lost all of its MPs, meaning that it only existed for 10 months.
Is this the shortest time that a UK political party has ever existed, from foundation to dissolution? The party also participated in the 2019 European elections, so is it also the shortest lived European political party?
