FILE - In this Tuesday March 12, 2019 file photo Britain's Prime Minister Theresa May speaks to lawmakers in parliament, London. Britain's love-hate relationship with the rest of Europe goes back decades, but the Brexit crisis gripping it today stems from dramatic January 2013 speech by Prime Minister David Cameron in which he promised an "in or out" referendum. Britain voted to leave, but negotiations between Britain and the EU have been slow and at times acrimonious, and the 585-page withdrawal agreement produced after two years of talks has been rejected twice by Britain's divided Parliament.
