The United Kingdom has seen a lot of political shuffling in the wake of the vote to leave the European Union.
Here's your guide to understanding it:

The Conservative power void:
Prime Minister David Cameron resigned the day after the referendum vote, taking the fall for calling the referendum and campaigning hard for Britain to remain in the EU.
There are five candidates vying to replace him and the betting is on Home Secretary Theresa May.
She is considered a steady hand in a turbulent time. But she campaigned for Remain in the referendum and hasn't done much to curb immigration – a big issue for many who backed Brexit.
Her main challengers – Energy Minister Andrea Leadsom and Justice Secretary Michael Gove – backed Vote Leave and both have insisted that the next Prime Minister should be someone who supports Brexit.

Boris Johnson, who decided not to run after being undercut by Mr. Gove, has kept largely out of public view but managed to write his regular column in the Daily Telegraph on Monday in which he mocked those who support the EU and called on the government to move quickly to come up with a Brexit plan.

Mr. Farage said on Monday that he is quitting for good this time, though he plans to remain as a member of the European Parliament and to keep active within the party.
Likely successors include Mr. Carswell and two UKIP MEPs; deputy party leader Paul Nutall and Steven Woolfe, the party spokesman on immigration.

Liberal Democrats:
The party elected MP Tim Farron as leader last July. He replaced Nick Clegg who resigned after the party’s disastrous showing in the general election when it won just eight seats.
The timeline:
Prime Minister David Cameron steps down.
Labour party veteran MP Hilary Benn launches a revolt against leader Jeremy Corbyn. Mr. Corbyn fires Mr. Benn from his shadow cabinet post.
Dozens of Labour MPs quit their shadow cabinet posts in a bid to force out Mr. Corbyn. Hundreds of activists hold a rally outside Parliament to support Mr. Corbyn.
Labour MPs hold a non-confidence vote in Mr. Corbyn's leadership, it passes 172 to 40. Mr. Corbyn refuses to quit.
Labour MP Angela Eagle announces she will force a leadership vote against Mr. Corbyn if he doesn't resign.
Mr. Johnson announces he will not run for the leadership.
Home Secretary Theresa May, who backed the Remain side in the referendum, announces she will run for the Tory leadership, making her the new front runner.
Labour Party officials scramble to find a solution to the growing leadership crisis and consider some kind of mediation.
Nigel Farage resigns as leader of the United Kingdom Independence Party.
Ms. Eagle reiterates that she will challenge Mr. Corbyn's leadership unless he resigns. Mr. Corbyn says he is staying put.
330 Tory MPs begin the first round of voting to select two leadership candidates. The finalists will be submitted to party members for a vote to determine which one will become the new leader.
Five MPs are running for leader: Ms. May, Mr. Gove, Ms. Leadsom, Liam Fox and Stephen Crabb. Ms. May is believed to have the support of more than 100 MPs, Ms. Leadsom around 30, Mr. Gove and Mr. Crabb around 20 each, and Mr. Fox about 10.
