Inside the shadowy (and very lucrative) world of Blair Inc: How the ex-PM has become a one-man multinational money-making machine.

I've got to hand one thing to George W. Bush, so far after his Presidency he has not so crassly exploited his time in power to the extent of former Prime Minister Tony Blair.

If you were to take Mr Blair's activities at his own evaluation, you would believe he divides his time between trying to save the world in the Middle East as the representative to that troubled region from the UN, the U.S., Europe and Russia; running his own faith and sports foundations in London; and organising various other charitable endeavours.

But the truth is a lot more complicated - and vastly more lucrative - than that.

At a conservative estimate, he has made £15million from his commercial activities since stepping down as prime minister in 2007, and there is every sign that his earning capacity is increasing.

He remains in demand as a £100,000-a-time international speaker, he has contracts to provide advice with several banking institutions, he is writing his memoirs, and he has established Tony Blair Associates (TBA) to provide advice to foreign governments for money.

There is nothing wrong with all this - except that he is pursuing his commercial interests so closely in tandem with his charitable work and job as an envoy to the Middle East that it is hard to see where the not-for-profit element ends and his own personal bank account begins."
