Article 50
From ACT Wiki
European Union - Brexit
'Article 50' deals with the procedure and timetable for a member state - for example the UK - to leave the European Union (EU).
Article 50 is part of the Lisbon Treaty of 2007.
It outlines a two-year timetable for negotiations, once a member state has notified its intention to withdraw from the EU.
The notification is often described as 'triggering' Article 50.
The UK formally triggered Article 50 on 29 March 2017, thereby establishing March 2019 as the timing of the UK's exit from the EU.
Any deal with the member state leaving the EU must be approved by a qualified majority of EU member states and can be vetoed by the European Parliament.
