Welcoming "a new, better deal for both the UK and the EU", the Conservative PM called on MEPs to "come together and rally the country" and adopt the deal, calling the vote on Saturday of "historic chance" to "achieve the Brexit" and to "allow the country to move forward" more than three years after the 2016 referendum. He also said that any further postponement of Brexit would be "useless, expensive and destructive ", before a vote that looks very tight on the exit agreement of the European Union concluded with Europeans.
