The negotiating period began on 29 March 2017, when the United Kingdom served the withdrawal notice under Article 50. Withdrawal was to occur on 29 March 2019, two years after the date of notification, as required by Article 50.
If the withdrawal agreement is ratified by the UK and other EU state governments and comes into force, negotiations to establish Free Trade Agreement treaties between the EU and the UK will be needed. In addition, the EU's existing Free Trade and WTOtariff-rate quotas with third countries (agreed while the UK was still a member) may need be split or renegotiated.
May resigned as leader of the ruling Conservative Party on 7 June 2019, and on 23 July, Boris Johnson was elected as her successor. As of 26 July 2019, the Johnson ministry has not reopened negotiations on the withdrawal agreement and has declared that the Irish backstop be scrapped as a pre-condition to doing so, which the EU has declared that it will not do.
