Crunch five days in Tory leadership race, writes BBC’s Laura Kuenssberg

First, on Sunday with Laura Kuenssberg, we’ll kick off with interviews with Badenoch and Jenrick (we have already spoken to the other two in recent weeks, you can watch those chats back here).

Next they’ll each be interviewed in the conference hall on Monday and Tuesday – a half-hour grilling followed by questions from the audience.

In the fringes, away from the public glare, the four are expected to attend at least twenty events – panel discussions, Q&As and a blizzard of press interviews.

Then their biggest test comes on Wednesday: a 20-minute speech that could make or break their leadership bid.

“They’re all hoping to do the barnstorming speech that makes people feel, wow, that’s definitely the person’,” says a former minister – to “do a Cameron“.

That’s a reference to 2005, when the Tories had been in opposition for years and the well known MP David Davis, a former minister, looked like the obvious new leader.

But suddenly, young shadow education secretary David Cameron – who I remember catching having a nervous smoke outside before his speaking slot – turned all that on its head.

His team had worked out he spoke more fluently and persuasively without autocue or a formal script, and he took only a few scribbled notes on the lectern. He wandered freely round the stage, telling the party it had failed and had to change from tip to toe.

It was a huge gamble – and he blew the crowd away.

Who’ll do it this time, whether they use notes or not?
