Sarah Wynn-Williams and Virginia Giuffre jointly win freedom to publish prize at British book awards

In a rare public appearance, Meta whistleblower Sarah Wynn-Williams warned of networks of powerful elites' using wealth and influence to silence dissenting voices

Meta whistleblower Sarah Wynn-Williams and the late Virginia Giuffre have jointly won the Freedom to Publish prize at this year's British book awards, marking the first time the award has been shared.

Wynn-Williams, a former Facebook executive, was recognised for Careless People: A Cautionary Tale of Power, Greed and Lost Idealism, her bestselling memoir about her years inside Meta, formerly Facebook. The book makes allegations about the company's internal culture and practices, including its approach to political influence, China and the wellbeing of teenagers. Meta has disputed the claims.
