"Trust me," Prime Minister Theresa May told other European Union leaders on Thursday, saying that with their help, she could win the British Parliament's backing for her Brexit deal and prevent a chaotic departure.

A day after a failed attempt to oust her by lawmakers in the governing Conservative Party, May told leaders of the other 27 EU members she believed there was majority in Parliament for her Brexit deal, she just needed a little more from them.

May postponed a parliamentary vote on the deal this week for fear of suffering a resounding defeat and is asking the EU to help her find a way to break the deadlock over Brexit, Britain's biggest shift in trade and foreign policy for more than 40 years.
