British Prime Minister Theresa May on Sunday pushed back on calls for a second referendum on Brexit, the United Kingdom's exit from the European Union. May particularly condemned remarks from former Prime Minister Tony Blair, who said this week a new vote should be considered if "none of the other options work." May accused Blair of "seek[ing] to undermine our negotiations by advocating for a second referendum," arguing "Parliament has a democratic duty to deliver what the British people voted for." May's proposed Brexit deal with the EU has stalled, lacking support to pass a House of Commons vote.
