John Christensen directs the Tax Justice Network, an expert-led network which has played a lead role in opening up debate on the role of tax in promoting sustainable development. Trained as an economist, he has worked in many countries and for 11 years was economic adviser to the government of the British Channel Island of Jersey. In 2003 he became what the Guardian has described as “the unlikely figurehead of a worldwide campaign against tax avoidance.” He is a member of the OECD Task Force on Tax and Development, and sits on the Board of the Washington-based New Rules for Global Finance. His research on tax and development has been widely published in books and academic journals, and John has taken part in many films, television documentaries and radio programmes. John is a Fellow of the RSA.
