Radix Big Tent 

The System Change Think Tank

Founded in 2016 by leading businessmen, Nick Silver and Joe Zammit-Lucia, Radix UK was a registered education charity, focussed on system renewal. From its outset, it has been an independent non-partisan platform for those outside the Westminster bubble to put forward ideas and contribute to political debate.

From its very beginning, Radix UK published influential papers, for example, calling for the Bank of England to be more political accountable, long before the idea became mainstream.

A year later, in the aftermath of the Brexit referendum, George Freeman MP (Conservative) and Baroness (Sally) Morgan (Labour) launched the Big Tent Foundation to promote cross-party debate and political engagement through an annual Ideas Festival, which came to be described as a “political Glastonbury”. Moving round the country - from Cambridge to Coventry, Bristol to York – the Big Tent Ideas Festival convened national and local businesses and politicians, not only to identify new public policy ideas, but also to create a legacy of local action and partnerships.

In 2019, Radix took responsibility for Big Tent’s political programming at its Festival in East London and then, in 2022, the two organisations merged to become Radix Big Tent.

Today, Radix Big Tent is a cross-party, independent think tank dedicated to the renewal of Britain by transforming not just what we do, but how we do it. We believe that real change requires system change.
