How effective is Labour's class war?

In today's Prime Minister's Questions, Keir Starmer went in on Rishi Sunak's privileged background. Starmer detailed the various facilities available at Winchester College, where Sunak was educated, from an art gallery to a shooting range. Is this an effective line of attack, or do voters simply not care? Katy Balls talks to James Forsyth and Fraser Nelson.
