EU's Donald Tusk says Irish border issue 'key' to progress in Brexit talks

European Council president Donald Tusk has warned Theresa May she must satisfy Irish demands that there will be no "hard border" between the Republic and the North if the Brexit negotiations are to move forward.

Following talks with Taoiseach Leo Varadkar in Dublin, Mr Tusk said it was now up to the UK Government to come forward with a "credible commitment" to deal with the border issue.
