Thousands of people took to the streets of central London March 23 to call for a second Brexit referendum amid a worsening political crisis over the U.K.'s departure from the European Union, Reuters reported.
Meanwhile, pressure for U.K. Prime Minister Theresa May to step down is mounting after her cabinet and the Democratic Unionist Party expressed lack of faith in her, The Times of London reported.
Organizers estimated that more than one million people turned out for the march in London, Reuters reported. A similar rally in October drew about 700,000 people, according to the report.
U.K. lawmakers recently voted 412-202 in favor of postponing Brexit to June 30 instead of the initial March 29. On March 21, the EU offered to delay the U.K.'s departure to May 22 but only if the U.K. Parliament draws up a Brexit deal within one week's time.
Prime Minister May previously ruled out holding another referendum, as it would deepen divisions and undermine backing for democracy, Reuters noted. Brexit supporters also said a second vote would lead to a major constitutional crisis.
The prime minister, who has been in office since July 2016, has reportedly been asked to set a date for her resignation, with even her allies believing her departure was inevitable.
David Lidington, May's de facto deputy, is said to have held discussions with opposition leaders about alternatives to May's Brexit deal, according to the Times report. The talks reportedly drew the ire of "Brexiteers" as it signaled that Lidington had taken control of matters, according to the report.
