Leo Varadkar and Theresa May are meeting today.
Their number one point of discussion will be Brexit, and how it will affect Ireland.
While they are both in Sweden for the an EU Summit, 98fm reports that they will have a private meeting to themselves.
It has been reported that Leo will reiterate the Good Friday Agreement, and tell the UK Prime Minister that a hard Northern Irish border is unacceptable under any circumstances.
As well as Mr Varadkar talking to Theresa, our Foreign Affairs Minister, Simon Coveney, is meeting with the British Foreign Secretary Boris Johnson at Iveagh House.
It is also expected that Brext will be on the top of the agenda.
