David Yelland and Simon Lewis discuss how the Palace is managing news of the King’s cancer diagnosis. How will the royal communications team be controlling the release of information in the coming weeks? Also, in the wake of Meta CEO Mark Zuckerberg’s apology to parents of children who have suffered on social media, David and Simon look at why real change is so hard in Silicon Valley when it comes to child safety, and the PR fallout. Is there a strategic communications plan that can stop tech billionaire Mark Zuckerberg’s reputation from crumbling? Perhaps the PR industry can learn a thing or two from climate activist Greta Thunberg?
