Starmer pressed on manifesto pledges and weight loss jabspublished at 08:48 British Summer Time
That's a wrap on the PM's interview on BBC Breakfast, but you can still watch it back on the top of this page by clicking the watch live button.
Keir Starmer was quizzed about Labour's manifesto promises, weight loss jabs, plus his pledge to build 1.5 million homes over the course of this Parliament.
"We were very clear in the manifesto that we wouldn't be increasing tax on working people and we expressly said that that was income tax, that was NICs etc," he said.
"So I'm not going to reveal to you the details of the Budget... what I will say is where we made promises in our manifesto, we will be keeping those promises."
On the government's examination of whether weight loss injections could get unemployed people back into work, Starmer said they could help reduce pressure on the NHS and boost the economy.
