About
I’ve spent my career at the intersection of high-stakes storytelling and digital transformation, from the corridors of 10 Downing Street to the campus at Google. My journey hasn’t been a straight line. I started in the newsrooms of BBC and ITV (eventually joining the launch team of 'Peston'). I then co-founded a creative agency (The Clerkenwell Brothers), working with some of Britain's most exciting brands. I joined Rishi Sunak as a special advisor in 2020 for a roller-coaster political career ending as the Head of Strategic Communications and Digital at No. 10. Today, I’m based in California, leading Executive Digital Communications at Google.On LinkedIn, I share insights on the future of communication, exploring how emerging tech is reshaping global narratives, the shifting design of digital government, and what Silicon Valley and Westminster can learn from one another. Follow along for a look at how tech, media, and politics are converging to change our world, and the occasional thriller book recommendation.
