(VOVworld) - The White House is urging Britain and the European Union to be "flexible" as they negotiate their breakup. White House spokesman Eric Schultz says the US is monitoring economic developments after Britain's High Court ruled that the government needs a vote in Parliament to trigger EU exit talks. The British Government has said it will appeal.  Schultz says the US wants the UK and the EU to work out Britain's exit through a "smooth, pragmatic, transparent and productive" process and that US will work closely with officials in London, Brussels and elsewhere throughout the process.
