BRUSSELS (Reuters) - European Council President Donald Tusk confirmed on Twitter that he had received Britain's Brexit notification letter on Wednesday, saying "After nine months the UK has delivered Brexit."
He tweeted a photograph of himself receiving the small, business-style white document from the British ambassador to the EU, Tim Barrow. It contains a signed letter from British Prime Minister Theresa May. Its delivery starts a two-year countdown to withdrawal at midnight, at the end of March 29, 2019.
