Donald Tusk gives Ireland crucial backing on border

If any proposal on the contentious issue of the border for Ireland is unacceptable, it would also be for the EU as a whole, declared Mr Tusk after a meeting in Dublin with the Taoiseach.
The statement by Mr Tusk effectively means Ireland will now have the final say on whether the UK can progress to the phase two of the Brexit negotiations. This will be decided in the coming days.
