The EU has accused Britain of violating the Brexit divorce deal by delaying border checks in N Ireland until October
Late-night talks between the EU and Britain to resolve a row over border checks in Northern Ireland ended without a breakthrough, officials said on Friday.
European Commission Vice President Maros Sefcovic and UK Brexit minister David Frost met on Thursday in Brussels as a wave of rioting has raised fears that fallout from Brexit is destabilizing the British province.
The European Union has also accused Britain of violating the Brexit divorce deal by unilaterally delaying border checks in Northern Ireland until October and launched a lawsuit against London last month over the issue.
This legal action will continue "as long as necessary," the EU said in the statement after the talks.
In the talks, Sefcovic insisted "that solutions can only be found through joint actions and through joint bodies," the EU statement said.
The British side said that recent technical talks between Brussels and London "had begun to clarify the outstanding issues, and some positive momentum had been established."
However "a number of difficult issues remained and it was important to continue to discuss them," the UK statement added.
The UK agreed to "intensify" the talks and both sides said they would engage with businesses and civil society in Northern Ireland to try to defuse any further fallout from Brexit.
The talks are centred on a special protocol of the Brexit divorce deal designed to prevent the emergence of a "hard border" between the UK province Northern Ireland and the Republic of Ireland, an EU member.
The special arrangement shifts customs and regulatory checks to Northern Irish ports on goods arriving from mainland Britain, a very controversial move for communities in Northern Ireland loyal to London.
