UK Prime Minister Boris Johnson hailed a Brexit deal "that takes back control", after reaching an agreement with the European Union to leave the bloc.
The President of the EU Commission, Jean-Claude Juncker, said: "Where there is a will, there is a deal."
The leaders of the remaining 27 EU member states have united behind the deal. It will now have to be ratified by the UK parliament on Saturday.
The Brexit breakthrough comes ahead of a key EU summit in Brussels today. Follow the latest developments in our live blog below:
