BRUSSELS—British Prime Minister Theresa May, seeking to unblock stalled talks on Brexit, promised on Thursday to make it as easy as possible for European Union citizens living in Britain to stay after it leaves the bloc.
Weakened by losing her Conservative Party’s majority in a June election and failing to rally support at an ill-fated party conference, May had initially hoped she would regain her footing by persuading EU leaders at a two-day summit starting on Thursday to let Brexit talks move beyond matters of the divorce.
