The former prime minister Tony Blair has received millions of pounds through an unusual mixture of commercial, charitable and religious income streams. Since he stepped down from office in 2007, his financial affairs have been described by observers as "Byzantine" and "opaque". The Guardian is now launching an online competition offering a prize to the person who can shine the brightest light on those financial structures.
Blair has a commercial consultancy, called Tony Blair Associates, plus jobs advising a US bank and a Swiss insurer. He has a multimillion pound book deal. He also has a charity, the Tony Blair Africa Governance Initiative, and another called the Tony Blair Faith Foundation. But much of the income, which includes charitable donations from other sources, has been funnelled through a structure called Windrush Ventures No 3 Limited Partnership. Our contest asks: what is Windrush?
Blair has a complex web of structures involving 12 different legal entities handling the unprecedented millions he is receiving since he stepped down from office in 2007.
