British Prime Minister Theresa May made her case Saturday for a new security treaty with the EU from next year, winning support from EU and U.S. officials who agreed the issue was too important to risk getting subsumed in broader Brexit negotiations.

In a speech to Western leaders and officials in Munich, May promised that London would continue to lead military missions and share intelligence if Brussels agreed to a pact "effective from 2019," the year Britain is due to leave the bloc.

May's government is using a series of speeches to set out its vision for Britain outside the European Union. But the loudest applause during her appearance came when the event's organizer, German diplomat Wolfgang Ischinger, said: "Things would be so much easier if you stayed."
