Agreeing Brexit backstop deal an 'issue of trust', says Varadkar

Update 6.10pm: The Taoiseach has said that the key issue of agreeing the backstop deal is not only an issue of substance but "an issue of trust".

Leo Varadkar reiterated Ireland's position on the backstop, which he said must be legally operable and would prevent a hard border emerging between the North and the Republic.
