Brexit trigger a moment of truth for UK, Europe and Asia

Nine months after it voted in a referendum to leave the European Union, Britain has given notice of its departure. In a move partly designed to warn markets, the British government on Monday pre-announced it would formally notify the EU on March 29 of commencing the countdown to leaving the EU. The EU and the U.K. will then begin at least two years of negotiations to determine exactly how this process will unfold. Already it is clear that the Brexit process will be acrimonious.
