Carole Cadwalladr is a journalist with The Observer. She was educated at Radyr Comprehensive School in Cardiff and Hertford College, Oxford. She recently won the Orwell Prize for Journalism 2018 for her reports on Cambridge Analytica and the impact of big data on the EU referendum and 2016 US presidential election.
Her investigation exposed Cambridge Analytica’s alleged harvesting of the data of 50m Facebook users to influence Brexit and Trump’s election. Cadwalladr’s reporting led to a public apology from Facebook’s Mark Zuckerberg and the suspension of Cambridge Analytica chief executive Alexander Nix. She described the experience of following the story as “like being strapped to a freight train for the last 18 months”.
