Labour should be prepared to offer voters the option of staying in a reformed European Union if the Government fails in the Brexit negotiations of “unparalleled complexity”، Tony Blair has said. The former Prime Minister also repeated his stance that he believed it was “possible” the public mood over the result of the referendum would change if Theresa May failed to deliver the promised benefits. Labour، Mr Blair added، should be prepared to capitalise on this potential scenario. Independent reported. His comments come as Ms May prepares to trigger Article 50، the untested mechanism for a member state leaving the union، starting the countdown on Britain’s two-year exit from the EU. She is expected to invoke the mechanism before the end of her self-imposed deadline of the end of March.
