Could Jeremy Corbyn be PM? Could there be a 2019 General Election after Theresa May’s resignation?
THERESA May is stepping down and a new Tory leader is soon to take over, but is this the time for Labour to swoop in?
Here's what we know about the nuts and bolts of calling a General Election - and how Jeremy Corbyn could take the top job.
Could Corbyn be the next PM?
Theresa May resigned on May 24 and on June 7 she officially stepped down as leader of the Tory Party.
The leadership contest has whittled down to just Boris Johnson and Jeremy Hunt, and one of them will take over at the end of July.
Boris Johnson is currently the bookies' favourite to replace Theresa May with odds of 1/14, according to Paddy Power
Jeremy Hunt is trailing behind with odds of 14/1.
But Jeremy Corbyn will not have a chance of becoming Prime Minister until a General Election is called.
Corbyn suffered a fresh poll collapse as voters punished his constant flip-flopping on Brexit.
Millions of former Corbyn supporters are apparently switching to the Remain parties - in a mirror image of the way ex-Tories have deserted Theresa May for Nigel Farage.
But now, he has announced that the Labour party will back Remain if a second Brexit referendum is called.
How could another General Election be called?
It's complicated.
The Fixed-term Parliaments Act 2011 dictates that a full term lasts five years. Before that legislation came in, it was possible to call an election with just six weeks notice.
As per her five-year term, Conservative leader Theresa May is signed up to the top job until 2022.
But since the PM called the disastrous 2017 snap election that lost her Commons majority she has struggled to make much headway at all with Brexit - her most pressing task at hand.
This has contributed to her increasing loss of authority, as MPs on both sides of the benches question her ability to cut a deal they're happy with.
On December 12, 2018, May faced her biggest test yet after enough Tory MPs called for a vote of no confidence in her leadership.
She won the challenge, and cannot be challenged again - including from Jeremy Corbyn - for an entire year.
However, after the Commons rejected May's Brexit deal 432 to 202, Corbyn tabled a vote of no confidence in the PM's government.
This is different than the challenge May faced in December because her party's MPs challenged her leadership.
The vote went in May's favour.

Is this likely? What has Labour said?
Tory MPs from both the pro-Brexit and pro-EU wings of the party warned they could face an electoral disaster if she goes to the country early.
Labour deputy leader Tom Watson has called for a national unity government.
In an interview with Prospect magazine, he said: "I prefer Labour governments and I hope we never get to a point where our economy or security is so in peril that we get a government of national unity."
But shadow transport secretary Andy McDonald, a reported Corbyn ally, told the BBC Today programme a unity government "is not the solution".
Conservative Party chairman Brandon Lewis also rejected the idea, insisting a national government is not the answer.
