The Liberal Democrats have pledged to cancel Brexit if they come to power at the next general election. Members voted for the new policy at their party conference in Bournemouth after it was moved by their former leader, Sir Vince Cable.
Previously, the party has backed another referendum or "People's Vote", saying they would campaign to Remain. The leader, Jo Swinson, said the manifesto pledge made the LibDems the "stop Brexit party".
In his first speech at conference as a Lib Dem MP, Chuka Umunna - who left Labour over its Brexit stance - said it would give the party a "clear unequivocal position". He said: "For three years Liberal Democrats have led the fight to stop Brexit. Our position is not only right, but has helped secure us incredible election results. This [policy] will stop this national embarrassment and enable us to focus on the things that really matter."
The motion, which was passed by an overwhelming majority, said that if the party became the government at the next general election, it would revoke Article 50 - the law that ensures the UK leaves the EU.
Earlier, Ms Swinson told the BBC's Andrew Marr show: "If people put [the Lib Dems] into government... the stop Brexit party, then stopping Brexit is exactly what people will get. Everybody can see we are stuck, that Brexit is in a mess. There needs to be a way out of that."
