The prime minister has faced criticism for leaving the 80th anniversary D-Day commemorations early to record a TV interview that's due to go out next week.    Rishi Sunak has since apologised - saying that "on reflection" leaving early "was a mistake", but also that it shouldn't be politicised.   Niall Paterson looks at how damaging this misstep is for Mr Sunak with Claire Pearsall, former Conservative special adviser at the Home Office, and Joe Twyman, the co-founder of the polling company Deltapoll.   Plus, our chief political correspondent Jon Craig tells us just how big of a political blunder it was. Producer: Sydney Pead Promotions producer: Jada-Kai Meosa John  Editor: Wendy Parker
