Today is the day that Britain files Article 50, it's formal notice of intent to withdraw from the European Union. By triggering this Article, Britain agrees to leave the bloc by 29th March 2019.
From then on, treaties that govern membership of the EU will no longer apply to Britain.
The terms of exit will be negotiated between Britain’s 27 counterparts, and each will have a veto over the conditions.
After the Brexit, Britain will be able to self govern again, create its own trade routes, control its borders, and will no longer be required to pay into the EU, which currently costs £50m per day.
Since joining the EU, Britain has been largely prohibited from trading with countries outside of the European Union.
It is hoped that the UK will re-open trade routes with the Commonwealth. The Commonwealth is the remnants of the original British Empire and is a voluntary association made of 52 sovereign states, including Australia, New Zealand, Cyprus, Malta, Canada, Jamaica, Trinidad, India and Pakistan.
You can listen live and debate the exit, in London City today from 12pm UK time (4am SL) and enjoy the street party and VE dances.
