Watch David Cameron Speak After Britain Votes to Leave E.U.

British Prime Minister David Cameron was due to speak outside 10 Downing Street on Friday morning, hours after voters rejected his Remain campaign and elected to leave the European Union.

He was expected to address the state of the markets, which have been highly volatile since the Leave vote began looking like a possibility. The London Stock Exchange is due to open at 8am. The Bank of England said it would take “all necessary steps” to guarantee economic stability in the wake of the vote.
