>> In the dramatic surroundings of Salzburg Theater, Theresa May took to the stage on Wednesday. The British Prime Minister appealing to EU leaders to drop Brexit demands on the border between Northern Ireland and EU member Ireland that she says could rip the United Kingdom apart. This summer dinner was held in one of the filming locations for The Sound of Music.
But May's overtures were met with the sound of silence. EU leaders listening politely, but they're maintaining a united front, refusing to let May circumvent the negotiations run by the European Commission's Michel Barnier. Instead, they discussed the issue at lunch on Thursday without the British PM. And on Thursday morning, they made it clear that May needs to give them guarantees on the Irish border if she wants them to give her the Brexit deal that would avoid the UK crashing out of the bloc.
>> We have very clear principles regarding the integrity of the single market, and regarding precisely the Irish border. It was presided in March, and it was endorsed by the 27 members. So we have to find collectively, and we need the UK proposal precisely preserving this backstop in the framework of a withdrawal agreement.
>> The UK says customs and trade arrangements at what will be its only land border with the EU will be resolved during a transition period of the Brexit. But the Europeans want an insurance policy to avoid a hard border in case those negotiations break down. Brussels proposing keeping Northern Ireland in a customs union with the bloc if talks fail.
That's been rejected by the UK, though a government source suggested Britain would come up with other proposals in due course.
