The Taoiseach says it's not up to Ireland to redesign the new border after Brexit - because Brexit is not Ireland's idea.

In his strongest-worded comments yet on Brexit, Mr Varadkar said leaving the EU was not an Irish policy and it wasn't up to Ireland to design the solution to Britain's departure.

It comes after British complaints that Ireland was seeking a sea border between the two islands after Brexit takes effect.

Unionists in the North are also angry.

But Leo Varadkar says if anyone should be angry about the process, it's Ireland.

It's the United Kingdom, it's Britain that has decided to leave; and if they want to put forward solutions - smart solutions, technological solutions, borders of the future and all of that - that's up to them", he said.

"What we're not going to do is design a border for the Brexiteers.

"If they're the ones who want a border it's up to them to say what it is, say how it would work and first of all convince their own people, and their own voters, that this is actually a good idea."
