*EDITORS PLEASE NOTE: EDIT NOW CONTAINS FRESH FOOTAGE OF THERESA MAY* (SOUNDBITE) (English) BRITISH PRIME MINISTER THERESA MAY SAYING: ''But it is now clear to me that it is in the best interests of the country for a new prime minister to lead that effort.
So I am today announcing that I will resign as leader of the Conservative and Unionist party on Friday June 7 so that a successor can be chosen.'' Britain's Brexit turmoil ushered in Theresa May's premiership...and now it's ushered her out.
The prime minister caved in to a cabinet mutiny and announced a date for her departure Friday.
(SOUNDBITE) (English) BRITISH PRIME MINISTER THERESA MAY SAYING: ''But with enormous and enduring gratitude to have had the opportunity to serve the country I love.'' May has three times failed to get parliamentary support for her Brexit deal.
Defeated by some devastating margins.
Her last gambit, and her undoing, was to make one final push to return the deal to parliament for one final vote, But newly added compromises proved too much for the Brexiteers among her ministers.
The two things that triggered the revolt?
The offer of a vote on holding a SECOND Brexit referendum - and closer trading arrangements with the EU after the UK's departure.
She also reached out to the opposition Labour party to try to find a last-ditch compromise.
That went down like a lead balloon.
Britain is supposed to leave the European Union on Halloween this year.
But with the political landscape changing by the week - it's still not certain when, how or even if Brexit will happen.
One factor will be how divisive May's successor is.
Ambitious conservatives have been circling for months, waiting for her demise.
Many believe the next prime minister will be less willing to attempt a balancing act, more likely to be staunchly pro-Brexit.
That could deepen the rift and could bring forward a general election.
May promised to leave months ago -- once her Brexit deal was passed.
The first concrete sign of the backlash that sped up her departure came Wednesday night, when high-profile Brexit-supporter Andrea Leadsom quit.
Leadsom was leader of the House of Commons and said she couldn't announce the new withdrawal agreement in parliament because she didn't believe in it.
May's deferred departure date means she'll still be in office -- though perhaps just in name only -- when U.S. President Donald Trump pays a controversial state visit to the UK in early June.
