Britain will have a new Prime Minister this week as Theresa May steps down after a tumultuous three years in office.

The Conservative Party has polled 160,000 members to decide who will succeed her as leader of the party - and of the country.

From a crowded field of ten, only two now remain - Boris Johnson and Foreign Secretary Jeremy Hunt .

The result will be announced today at around 11am. Mr Johnson is widely expected to win.

Here's your guide to how the next few days are expected to play out - and the key moments in a historic week for the country. 

Monday July 22

Monday was the calm before the storm after the postal ballot closed in the Conservative leadership election yesterday.

Boris Johnson is the bookies favourite to become the next PM and he has promised to take the country out of the EU 'do or die' on October 31.

But could Jeremy Hunt deliver a stunning upset? He's been unable to shake his 'remainer' allegiance he held during the EU referendum in 2016.

Tuesday July 23

The UK's new prime minister will be announced today at around 11am. Tory chiefs have not confirmed where or how this will happen.

Theresa May will remain in post for the next 24 hours after a widely criticised premiership which has been scuppered by her failure to get a Brexit deal through Parliament.

Regardless of the winner, there could be a slew of Cabinet resignations from the likes of Chancellor Philip Hammond who do not wish to allow Mrs May's successor the pleasure of sacking them.

Wednesday July 24

This will be the day it all happens.

At 12pm Theresa May will deliver her final PMQs in Westminster and afterward it is expected she will give a farewell statement, possibly with her ever-supportive husband Philip May at her side.

She will then be driven to Buckingham Palace to meet the Queen and formally resign.

Soon afterwards the new PM will also head to Buckingham Palace to be appointed by the monarch.

He will then return to Number 10 as Prime Minister for the first time and is expected to give a speech.

The new premier will then begin appointing his Cabinet, including the key posts of Chancellor of the Exchequer, Home Secretary, Foreign Secretary and Health Secretary.

Thursday July 25

The Commons sits at 11.30am, the last day before the summer recess.

It is possible there will be a statement by the new Prime Minister and during the day other Cabinet and government roles are expected to be handed out to Conservative MPs.

If Labour are to attempt to force a vote of no confidence, now is the time. If they successful a vote will be held at 5pm.

And if that passes? Well, let's cross that bridge when we come to it.

Friday July 26

If the vote of no confidence has failed, or if there isn't one, then Friday will be a relatively quiet day with the last few government jobs handed out by the new Prime Minister.
