LONDON – British Prime Minister Theresa May announced Friday that she will resign – ending her months-long struggle to keep her job despite seething anger from her own Conservative Party over her handling of Brexit.
Here is a timeline of key events in how Brexit unfolded and how the political crisis led up to Theresa May's ouster as British prime minister:
May 7, 2015: British voters elect a majority Conservative government. Then-Prime Minister David Cameron confirms in his victory speech that there will be an "in/out" referendum on Britain's EU membership.
Feb. 20, 2016: Cameron confirms that he will campaign for Britain to remain in the 28-nation bloc. The referendum date is set for June.
June 23, 2016: Britain votes 52 percent to 48 percent to leave the EU.
June 24, 2016: Cameron says he will resign in light of the results.

Oct. 2, 2016: May says that Britain will begin the formal process of leaving the EU by the end of March 2017. In order to do this, the British government would have to invoke Article 50 of the EU's Lisbon Treaty.

July 7, 2018: May and her Cabinet endorse the so-called Chequers Plan worked out at a fractious session at the prime minister's country retreat. It leads to the resignations of Brexit Secretary David Davis, Foreign Secretary Boris Johnson and others who favor a more complete break with the EU.
