Prime Minister David Cameron warned Monday that a vote to leave the EU would risk Britain's economic and national security, as uncertainty over the outcome of the June referendum sent the pound plunging. In a speech to the House of Commons, the Conservative leader launched a barely-veiled attack on London mayor Boris Johnson, his long-term rival who has come out for a Brexit, accusing him of taking the position for political gain. As sterling fell to a near seven-year low against the dollar on the currency markets, Cameron told lawmakers that it was time to "properly face up to the economic consequences of a choice to leave".
