LONDON (AP) — British Prime Minister Theresa May is meeting a leader of her Conservative lawmakers amid mounting speculation that she is about to announce her departure date.

The party's key backbench committee has set a showdown meeting Friday for May to agree to leave soon or face a leadership challenge.

Pressure on May to quit over her failure to get Parliament's approval for a European Union divorce deal reached critical point this week as a senior minister quit and several Cabinet colleagues expressed doubts about her Brexit bill.

Several British media outlets reported that May would agree to give up the prime minister's post June 10, sparking a Conservative leadership contest.

She could stay in office as a caretaker prime minister for several weeks until party lawmakers and members choose a successor.
