Brexit means Brexit and we're going to make a success of it.

We have got a cast iron assurance and a guarantee from the British government.

The particular problems around the Irish border are being used politically to try to frustrate Brexit.

Northern Ireland must lead the European Union on the same terms as the rest of the United Kingdom.

Northern Ireland would form part of our customs territory.

Hello and welcome to Brexit Republic, RTE's podcast on Brexit.

I'm Tony Connolly, RTE's Europe editor at the EU Budget Summit in Brussels.

I'm Sean Whelan, RTE's London correspondent in Westminster.

And I'm Cullam O'Monghoyne RTE's Deputy Foreign Editor in Dublin.

Each week, Brexit Republic assesses all the latest Brexit developments in Brussels, London and Dublin.

This week, Mr Frost comes to Brussels.

Yes, Boris Johnson's chief negotiator, David Frost, enlightened an audience of students and think tankers in a Brussels university

on his countries and his own personal journey into Brexit.

and what the big differences still are on the vexed question of the level playing field.

And we'll be looking at the Brexit-sized hole in the EU budget,

75 billion euro in counting,

and what that will mean for Ireland's net contributions over time.

Okay, well, Sean, we'll go from the cold atmosphere at the European summit
