LONDON (Reuters) - British Prime Minister Theresa May is totally focused on the job at hand and will remain so, her spokesman said, as rumors swirled that she would set out a timetable for her departure to her Conservative lawmakers later on Wednesday.

The spokesman also said the government would only bring back her twice-defeated Brexit deal for a vote in parliament when there is a realistic prospect of success.

Some Conservatives have suggested they could back the deal if May agrees to step down before the next phase of negotiations with the EU.
