More than two years after the United Kingdom voted to leave the EU, it is still unclear how, on what terms or even if it will leave the EU as planned on March 29, 2019.

May, who won the top job in the turmoil that followed the 2016 referendum, has sought to negotiate a Brexit deal that ensures that the United Kingdom leaves in the smoothest way possible.

But Brexit Minister, Dominic Raab, resigned on Thursday over her deal, sending the pound tumbling. Mutinous lawmakers in her own party, openly sought to challenge her leadership and bluntly told her that the Brexit deal would not pass parliament.

May, who has vowed to stay on as Prime Minister, was asked by a caller on radio phone-in on Friday to “respectfully stand down”. She reportedly did not immediately address that part of the caller’s question.

May said she had not appointed a new Brexit Secretary yet, but will be doing that over the course of the next day or so.

Many said that Brexit will pitch the world’s fifth largest economy into the unknown and there are fears it will divide the West as it grapples with both the unconventional U.S. Presidency of Donald Trump and growing assertiveness from Russia and China.

Amid the deepest political turmoil since the Suez Canal crisis, when in 1956 Britain was forced by the United States to withdraw its troops from Egypt, the ultimate outcome remains uncertain.
