Keir Starmer: “I have seen the body cam footage. It's harrowing.”

I will now focus on other things and that will be international affairs including defence, security, trade and technology in a fast-changing world.

It’s work I started before I became an MP and it’s work I’m keen to continue after I’m an MP.

They have been resolute in their support for me, firstly in becoming an MP and then becoming the leader of Labour party and then as prime minister.

I think once you’ve been prime minister, it’s important to answer the question: what are you going to do next? Having decided I’m going to concentrate on international affairs, I think it’s right to step down.
