Taoiseach Leo Varadkar has said any suggestion that a new Brexit deal would be negotiated by Boris Johnson and the European Union was "totally not in the real world".

Speaking on RTÉ's Six One, he said he wanted to hear the new British Prime Minister put some "flesh on the bones" of the claims he made in his speech earlier today, and said that "confidence and enthusiasm were not a substitute for a European foreign policy".

Mr Varadkar said that listening to what Mr Johnson said today, he got the impression he was not just talking about deleting the backstop, but a whole new and better deal for Britain.

"That is not going to happen. The EU council doesn't meet until 12 October. We have no plans to meet any earlier."

"Any suggestion that there would be a whole new deal negotiated in weeks or months is totally not in the real world".

Mr Varadkar said that what Mr Johnson wanted was clear, but was not detailed.

He congratulated Mr Johnson and said it was an enormous privilege and honour to lead the country.

He said the Irish Government looks forward to working with him in the future, to discuss issues on Brexit, bilateral relations and Northern Ireland.

He said we have to deal with the situation as it is, and highlighted that it was a very unstable political situation in the UK.

He said Ireland was stable, with clear policy and solid support from other EU states.

Mr Varadkar said Brexit has damaged relations between UK and Ireland, and said Britain had made the decision to leave the EU without thinking it through.
