Theresa May has signaled to Tory MPs that she will resign as prime minister once the U.K. has formally quit the European Union.
May had previously indicated that she would step down before the next general election, but Wednesday's announcement indicates that she would leave the position far earlier than previously thought.
In December, after a third of her MPs voted to oust her, the PM told her party that she would not lead them into the next general election.
But since then she has come under intense pressure from pro-Brexit lawmakers to clarify that she would not remain in No.10 for the "next phase" of talks with Brussels on a future U.K.-E.U. trade deal.
Although MPs had not pushed for a specific resignation date, many wanted May to clarify she would not be in charge once the formal divorce with the E.U. had occurred.
On Tuesday, a source told HuffPost UK that influential Tory MP Sir Graham Brady pushed the PM for more "clarity" on her future plans.
