Blair suggests a second referendum for UK
The former UK PM has said the country should keep its "options open" over Brexit that might mean a second referendum.
In an interview to BBC, Tony Blair said the vote was a "catastrophe" and said it was vital to study the "real-life implications".
Mr. Blair said he accepted the decision of June's referendum, but recommended looking again at Brexit when "we have a clear sense of where we're going".
Former premier also voiced a concern that the views of the "16 million" people who had backed remaining in the EU should not be ignored.
He added: "If it becomes clear that this is either a deal that doesn't make it worth our while leaving, or alternatively a deal that's going to be so serious in its implications people may decide they don't want to go, there's got to be some way, either through Parliament, or an election, or possibly through another referendum, in which people express their view."
But he also said that the vote is unaltered "unless it becomes clear that the British people have had a change of mind".
