British Prime Minister Theresa May looked likely to survive any attempt to oust her over the government's Brexit strategy for now, and is leaning on the biggest opposition party to help get the plan through parliament and counter a mutiny by a group of her own lawmakers.

Despite the resignations of two of her most senior ministers in one day including her foreign minister — an event without parallel in recent decades — most of her Conservatives appeared content on Monday evening with a proposal that would keep Britain close to the European Union on trade and regulations.

A handful of lawmakers who want a clean break from the EU said privately they had submitted letters calling for a vote of confidence in May, though hadn't met the threshold of 48 needed to trigger such a ballot. But should they ultimately do so, the prime minister also looked to have enough support.
