Pound hits 31-year low on "hard" Brexit worries while UK stocks soar

By Anirban Nag and Sudip Kar-Gupta LONDON (Reuters) - Sterling slid to its lowest level in more than three decades on Tuesday on fears of a "hard Brexit" from the European Union and its single market, although the weaker pound sent UK stocks surging higher. The pound has already lost 1.7 percent against the U.S. dollar since Prime Minister Theresa May said on Sunday the formal process to take Britain out of the EU would start by the end of March 2017.
