Inside Europe: Brexit Day and an unknown future for the UK

They're calling it “Brexit Day “ - March 29th - the day when UK Prime Minister, Theresa May, triggered the process that will lead to the UK’s departure from the EU. A momentous event; Britain is pulling out of a single market which buys more than 40% of its exports. The EU is losing the world’s 5th largest economy and the 2nd biggest contributor to its budget.
