Richard Murphy is a chartered accountant who, after a career as a partner in private practice and commerce, helped found the Tax Justice Network in 2003. As technical adviser to that group, he created country-by-country reporting, which is now in use for tax reporting around the world. He also promoted the study of the tax gap as a way of appraising risk in the economy, and this is the focus of much of his recent work. Now a professor at City, University of London, his ideas have been used by many politicians, including David Cameron, Caroline Lucas, Vince Cable and Jeremy Corbyn. Richard was rated the ninth most influential person in worldwide tax by International Tax Review in 2017. He writes frequently about political and economic matters on his blog Tax Research UK and is the author of The Joy of Tax (2015).
