European Union and U.K. negotiators agreed on an outline of future U.K.-EU ties, taking Britain a step closer to an orderly departure from the bloc with a document British Prime Minister Theresa May hopes to use to rally domestic support for her Brexit deal.

The draft, which leaves open a range of future economic arrangements, comes about a week after the EU and U.K. reached a so-called withdrawal agreement, a legally binding document that spells out critical terms for Britain’s planned exit from the bloc next March.
