The UK formally leaves the EU on 31 January 2020 - which will be followed by months of negotiation during what's known as the 'transition period'.
This allocated period should give both sides time to negotiate a new deal. After the 11-months is up, the UK will leave the single market and customs union. Currently, a free trade agreement allows goods to move around the EU without checks or extra charges.
If a new one cannot be agreed in time, then the UK faces the prospect of having to trade with no deal in place. That would mean tariffs (taxes) on UK goods travelling to the EU and other trade barriers.
Aside from trade, many other aspects of the future UK-EU relationship will also need to be decided. For example:
Law enforcement, data sharing and security
Aviation standards and safety
Access to fishing waters
Supplies of electricity and gas
Licensing and regulation of medicines
