Gideon Rachman

Chief Foreign Affairs Commentator, Financial Times

Gideon Rachman translates his extensive travels and his remarkable access to world leaders into an insider’s view of global events. He speaks authoritatively about politics, economics and globalisation as they apply to Asia, Europe, the Middle East, the Americas, and more.

At the FT, Gideon writes a weekly column on international politics as well as feature articles. He has reported for the FT from all over the world. Before joining the FT in 2006, he worked for The Economist for 15 years in a range of jobs, including as a foreign correspondent in Brussels, Bangkok and Washington and as business editor.

His FT Podcast ‘The Rachman Review’ is amassing new listeners weekly – it was awarded as ‘International Podcast of the Year’ in 2025 by the annual Political Podcast Awards.

Gideon’s last book is ‘The Age of The Strongman: How the Cult of the Leader Threatens Democracy around the World‘ (April 2022) – this is now translated into 14 languages.  In this book, he finds global coherence in the chaos of the new nationalism, leadership cults and hostility to liberal democracy.   His prior book was ‘Easternisation: War and Peace in the Asian Century ‘ – this illustrated how the growing wealth of Asia nations is transforming the international balance of power. The Sunday Times called it as “masterly account” and the Daily Telegraph called it “superb“. Paul Kennedy of Yale University commented – “This really is one of those works where you can say you wished our political leaders had read and pondered its great implications.”

His book, Zero-Sum World,  predicted the current trade war between the US and China. It was published under the title Zero-Sum Future in the US in 2011. The New York Times called it “perhaps the best one-volume account now available of the huge post-communist spread of personal freedom and economic prosperity.” The Independent called it “an important timely book that should be obligatory reading for all interested in what is happening beyond our shores.” Niall Ferguson commenting on this book hailed it as ‘’An inimitable combination of dry wit and analytical clarity’.

His next book will be published in late Spring 2026.

Gideon received the 2016 Orwell Prize for journalism, Britain’s most prestigious prize for political writing and the 2016 European Press Prize: Commentator Award. Gideon also received the Overseas Press Club of America’s 2017 Best Commentary Award for the best commentary in any medium on international news. His columns continue to cover a wide range of global issues from the economics and politics of the euro-crisis, to US foreign policy and the rise of China.

He has also written for numerous other publications, including Foreign Policy, National Interest, The Washington Quarterly and Prospect magazines. He is a regular broadcaster for, amongst others, the BBC, CNN and NPR.

Rachman is also a regular speaker before both academic and business audiences. He has spoken to the Council on Foreign Relations in New York, the Brookings Institution, the London School of Economics, Oxford and Harvard Universities and the Royal Institute of International Affairs — as well as to Goldman Sachs, Barclays, CLSA, Morgan Stanley, Omnicom, Pictet, Jefferies, Euroclear and many other business audiences  

Gideon is a visiting fellow at the LSE IDEAS, a foreign policy think tank.

The Right Honourable Sir Tony Blair KG

Former Prime Minister of Great Britain and Northern Ireland

Former Prime Minister of Great Britain and Northern Ireland Tony Blair founded TBI on the belief that a country’s success and ability to enact transformational change is dependent on the effectiveness of its leadership and governance.

Under Tony’s direction, TBI works with political leaders around the world to create real change for their people by advising on strategy, policy and delivery – with technology as an enabler of all three.

During his tenure as prime minister, Tony implemented a major domestic-policy agenda. Through record investment and reforms, the performance of the UK’s education and health-care sectors was radically improved; crime was reduced by a third; a major programme of social liberalism and constitutional change was introduced; the Department for International Development was created and the UK’s foreign aid to Africa trebled; and landmark legislation to tackle climate change was introduced. All of this was done in the context of record economic growth and employment levels. Tony also helped bring peace to Northern Ireland by securing the historic Good Friday Agreement in 1998, and he was a passionate advocate of interventionist foreign policy. He is the only Labour leader in the party’s 100-year history to win three consecutive elections.

After leaving office, he continued his deep commitment to Africa and remained engaged with the Middle East, where he has long advocated for and worked towards the normalisation of relations between Israel and Arab states, contributing to the signing of the historic Abraham Accords in 2020.

Tony dedicates the majority of his time pro bono to TBI, a not-for-profit organisation.
