LONDON (AP) — The Latest on Conservative Party voting to pick Britain's next prime minister (all times local):

6:05 p.m.

The contest to become Britain's next prime minister is down to four candidates, with Boris Johnson building on his commanding lead in a Conservative Party vote.

Johnson gained 143 of 313 votes cast by Conservative lawmakers Wednesday in their third round of voting.

He's being chased by Foreign Secretary Jeremy Hunt, Environment Secretary Michael Gove and Home Secretary Sajid Javid. 

International Development Secretary Rory Stewart, a longshot candidate who energized the race, received the fewest votes and drops out.

Two more votes are scheduled for Thursday to whittle the field down to two. The final two contenders will go to a by-mail ballot of all 160,000 Conservative Party members nationwide. 

The winner is due to be announced in late July, and will replace Theresa May as party leader and prime minister.
