No deal can be secured on the Irish border after Brexit until trade negotiations are settled with the EU, UK International Trade Secretary Liam Fox has said.

He raised further uncertainty over Northern Ireland as rows over a potential hard border threaten to derail Brexit talks, The Independent reported.

Fox told Sky News on Sunday the final decision on the border could not be made until a UK-EU trade deal had been agreed – despite warnings from Brussels that trade talks cannot proceed until the border issue is settled.
