Douglas has been elected to Parliament four times, for two different parties – finishing up as an independent.
He co-founded Vote Leave, the official campaign group that won the recent EU referendum – and in April 2017 announced he would be standing down from Parliament, declaring his "job done".
According to Alex Massie of the Spectator, "By any reasonable measure, Carswell has been one of the most influential backbenchers in recent memory. Possibly, even, the most influential of all".
Douglas advises FTSE 100 firms at board / CEO level about the implications of Brexit. He has participated at the Königswinter conference, Anglo-French Colloque and this year's DigitalK.
An optimist who believes that the world is getting better, Douglas is very concerned about what he sees as the emergence of a political and economic oligarchy. It is this, he argues, that is fueling the rise of destructive, radical populism.
According to the BBC's Mark D'Arcy, Douglas enjoyed"One of the more remarkable - and effective - parliamentary careers of the 21st Century".
Douglas' book, Rebel: how to overthrow the emerging oligarchy, was published by Head of Zeus in April 2017. His earlier book, The End of Politics and the Birth of iDemocracy, anticipated many of the changes that we are now seeing throughout the Western world.
Before politics, Douglas had a proper job working for a FTSE 100 fund manager.
He is married to Clementine, and is a dad. He loves gardens and growing things.
Born in 1971, Douglas' home was in Uganda until his late teens. He read history at the University of East Anglia and King's College, London.
