Sir Keir Starmer could end up allowing Donald Trump to use British bases to launch strikes on Iran, Harriet Harman has said.
Speaking to Beth Rigby on the Electoral Dysfunction podcast, Baroness Harman said this was despite the prime minister being part of a generation "shaped" by opposition to the Iraq War.

Baroness Harman was solicitor general when Sir Tony Blair decided to take Britain to war in Iraq alongside the United States in 2003.
She said the decisions made by Sir Tony would be "burning bright" in Sir Keir's mind.
"He's part of the political generation of the Labour Party that grew up, which was shaped by its opposition to what Tony Blair was doing in relation to Iraq," Baroness Harman said.
"So it would be a massive change for him."
Asked if the UK could end up giving permission for US aircraft to use British military bases on Cyprus and Diego Garcia, but not go any further than that, Baroness Harman said: "Exactly".

Sky News reported on Thursday that Attorney General Richard Hermer has raised questions over whether Israel's actions in Iran are lawful, potentially limiting what support he believes the UK could offer the US.
Baroness Harman said that for Sir Keir, the "rules-based international order is the most important thing".
"If the attorney general says that the government can't do something because it's illegal, it can't do it. So he's in a very crucial position," she added.
But Baroness Harman said it would be difficult for Sir Keir to say "thank you for the trade deal" to Mr Trump and then deny the president use of the airbases.
