LKS 20170329 A newspaper stand shows an advert for today's Evening Standard newspaper, leading with the story relating to British Prime Minister Theresa May's triggering of Article 50 of the Lisbon Treaty to begin the process of Britain's withdrawal from the European Union (EU), in London on March 29, 2017.
