The Labour Party leadership of Jeremy Corbyn began when Jeremy Corbyn was elected as Leader of the UK Labour Party in September 2015, the election having been triggered by the resignation of Ed Miliband in the wake of Labour's defeat at the 2015 general election. At the same time Corbyn became the Leader of the Opposition. Corbyn faced a second leadership election in 2016, when he was challenged by Owen Smith, but was re-elected in September.
