LONDON (Reuters) - British Prime Minister Theresa May had a further telephone call with European Commission President Jean-Claude Juncker on Monday, her spokesman said, adding that the Brexit talks were continuing.

May also spoke to Juncker late on Sunday after calling EU leaders on Friday and Saturday to try to find a breakthrough in talks to gain concessions to the divorce deal from the bloc to make it more palatable to parliament.

May returns to parliament on Tuesday to put her deal again before lawmakers, who overwhelmingly rejected it in January. Without any changes to the deal, she could face another heavy defeat.
