The UK has struck a deal with the US to preserve £12.8bn of trade after Brexit.

International Trade Secretary Liam Fox said it would allow firms to “keep trading as freely as they do today”.
Earlier this week, Mr Fox came under fire for failing to ensure businesses trading overseas would be unaffected if the UK left the EU without a deal.
In that scenario, British companies would no longer be able to trade on the preferential terms the EU has agreed with about 70 countries.New UN special envoy hopes to convene Syrian constitutional committee soon
