What would it take for Sunak to have a breakthrough?
Some Conservatives have put their hopes on tonight's TV debate as a breakthrough moment for the lacklustre and disorganised Tory campaign, but will it really be a gamechanger? James Heale talks to Isabel Hardman about why she's sceptical, and to the pollster Chris Hopkins at Savanta about why the Tories just aren't closing that poll gap. Produced by Megan McElroy and Cindy Yu.
