Up until April 2021, Samuel served as special advisor to the prime minister.

Following his exit from 10 Downing Street, he took time out to travel, reflect, and write. He subsequently signed a book deal with Hodder & Stoughton. In Samuel’s new book “The Power of the Outsider” he uses reflections from his experience in government and the stories of other outsiders to explore a concept that he believe has not been fully investigated. The book is now available for pre-order via 

Samuel will also be embarking on a national speaking tour as part of the book publication.

The world is changing and opening opportunities that have been the preserve of elites. This has meant that there are more people of different backgrounds entering different areas for the first time, often with limited guidance about how to navigate them. As one of those people, I want to share how this has been a journey of discovery for me, and I hope it will be for readers too. This book is raw, it’s honest, and I hope it’ll be important.
