Why did Sunak leave the D-Day commemorations early?

It's yet another gaffe for Rishi Sunak. At yesterday’s D Day anniversary celebrations when it came time for official photographs with Joe Biden, Olaf Scholz and Emmanuel Macron, it was Lord Cameron, not Rishi Sunak, who did the honours for Britain. With the prime minister reportedly leaving early to do a pre-recorded political interview with ITV. He has since apologised, but can he bounce back from this one?  Oscar Edmondson speaks to Katy Balls and Isabel Hardman.  Produced by Oscar Edmondson.
