Britain is no longer the great power it once was. Caught between an unmoored America and a fractured Europe, it confronts rising authoritarian challenges from China and Russia, while its domestic debates drift into abstract moralising. Lacking a coherent vision for the future, the country risks sliding further into managed decline, its global relevance steadily eroding. Yet such a trajectory is not inevitable. In this clear-eyed assessment of Britain's economic, ideological and strategic vulnerabilities, Azeem Ibrahim identifies the essential building blocks of renewal. He outlines a programme of reforms that will allow a genuinely independent Britain to capitalise on its core strengths. After all, as a lean and specialised nuclear power with one of the world's most sophisticated intelligence networks, as well as world-class universities and a cultural reach second only to the US, the UK can still shape global affairs. A Greater Britain argues that a clear strategic anchor and bold leadership are needed if the UK is to convert its advantages into real influence. By formulating a pioneering Knowledge Power Doctrine, the book offers a global strategy for a once powerful nation, providing nothing short of a roadmap back to British greatness.
