May upbeat on UK's post-Brexit future

British Prime Minister Theresa May sought to reassert her authority with her keynote address to the Conservatives' annual conference on Wednesday, a day after Boris Johnson made an overt pitch for the leadership of the party.

Minutes before May literally danced on to the stage to make her speech in Birmingham, England, in a self-deprecating nod to her much-mocked dancing during a trip to Africa earlier this year, Conservative MP James Duddridge submitted a letter of no-confidence, urging her to quit as party leader.

May is under huge pressure to unite her party at the end of a conference which has exposed deep splits over her approach to Brexit.
