The UK's Brexit Secretary David Davis and the EU's chief negotiator Michel Barnier will hold talks in Brussels - with the Northern Ireland border set to feature on the agenda.

"A post-Brexit EU must take full advantage of Europe's collective strength and influence, but not limit the capacity of member states to respond quickly to external shocks," he continued.
