After the British EU membership referendum held on 23 June 2016, in which a majority voted to leave the European Union, the United Kingdom experienced political and economic upsets, with spillover effects across the rest of the European Union and the wider world. Prime Minister David Cameron, who had campaigned for Remain, announced his resignation on 24 June, triggering a Conservative leadership election, won by Home Secretary Theresa May. Following Leader of the Opposition Jeremy Corbyn's loss of a motion of no confidence among the Parliamentary Labour Party, he also faced a leadership challenge, which he won. Nigel Farage stepped down from leadership of the pro-Leave party UKIP in July. After the elected party leader resigned, Farage then became the party's interim leader on 5 October until Paul Nuttall was elected leader on 28 November.
