BY LOUIS MILMAN, IBTISSEM GUENFOUD(BRUSSELS, Belgium) -- The European Union and the United Kingdom have reached a trade and cooperation agreement days before the next Brexit deadline. The UK is set to leave the European single market and customs unions on January 1.The deal will allow for the UK to withdraw from the EU in an orderly manner. Ursula von der Leyen, President of the European Commission, said the deal the two sides reached was "worth fighting for," offering hope that both sides can now "leave Brexit behind us and look to the future."The deal will create two separate economic markets, which include their own regulations and laws. Some barriers to trades and cross-border mobility are expected in both directions.Still, in a statement, the EU says that not getting a deal done would have been economically damaging for both sides.In his own statement, UK Prime Minister Boris Johnson reflected on the more than four years since the British people voted to leave the EU.
