The Prime Minister talked about the challenges we face as a country, the crisis in the Middle East, the impact on the cost of living here, and that this government will do what we were elected to do, which is serve the British people.

So familiar scenes, if you like.

I was thinking about it when we heard those shouts of will he resign.

It was...

Similar to what we heard when, of course, the Conservatives were in power for 14 years.

But to sort of bring you up to date, where we are is a sort of tense standoff between the prime minister, Keir Starmer, making it clear to his cabinet and beyond that to the party, look, I'm not going anywhere unless someone challenges me.
