The Taoiseach says a positive vote in the House of Commons tonight will remove the dark cloud of Brexit from over Ireland.
British MPs will vote on the withdrawal agreement once again this evening after Theresa May secured legally binding assurances to the backstop.
It provides confirmation to the UK that the EU cannot try to trap it in the backstop indefinitely.
The assurances will need to be enough to persuade pro-Brexit Conservatives and the DUP in order to get the deal over the line.
Leo Varadkar says he hopes and trusts it will be passed by MPs this evening.
