Every decision I've taken has been about putting the country I love first.

That is why I will resign as leader of the Labour Party.

Kirstama has quit.

Andy Burnham is preparing for power. But what will a mid-parliament

change of prime ministers mean for the government? I'm Hannah White and this is Inside Briefing

the podcast from the Institute for Government. So the coronation of Andy Burnham is apparently

drawing nearer. Darren Jones, the chief secretary to the Prime Minister,

has ruled out standing for the Labour leadership, making it increasingly unlikely that there will be

a contest to succeed Kirstama. So, how should Andy Burnham use the weeks he has available to prepare

for the biggest job in government.

How should Kirstama, if he is inclined to do so, help him?

And as the UK prepares for its seventh Prime Minister in a decade,

what are the prospects of this period of intense volatility drawing to a close,

if even a Prime Minister with a huge majority can't survive for long in number 10.

All that to come in our discussions today, Kath Haddon, our senior fellow, is dialing in from Deptford.

Are you keeping cool there, Cass?

Yes, yes, I should be all right.

Here in the relative cool of our improvised podcast studio, which we decamped the room in the IFG that has air conditioning, I have with me Alex Thomas, our executive director for Impact, who has just returned from a week in Thailand. Was it hotter there or here, Alex?

It was probably about the same temperature, but it was considerably muggyer there, so I'd still take the British summer over the Thai steam.

And I am delighted that Hugo Jai, the new political correspondent at The Economist, has joined us in the studio.

Hi, Hugo.

Hello, thank you for having me.
