Leo Varadkar: UK customs union with EU has 'real merit'

The proposal for the UK to stay in a customs union with the EU after Brexit has "real merit", the Taoiseach (Irish prime minister) has said.

Leo Varadkar was speaking in Brussels ahead of a crucial EU summit.

Leaders are due to discuss the UK's request for another extension, to avoid a no-deal Brexit on Friday.

Mr Varadkar said Theresa May needed to show that there was a "plan for the extension to have a purpose".
