Now, I fully understand that President Obama will want to appoint some fellow persons of colour to key positions. Who we need in Grosvenor Square is Thomas Sowell. Not only is Sowell one of America's greatest economists, he is considerably blacker than Obama. And he's a keen photographer.
It's a no-brainer. And Tom can moonlight by teaching economics to Mr Brown and Mr Darling.
Should Sowell be unavailable, Alvin Hall is the obvious second choice.
