The Margin's quote of the week from Davos, came not from Bill Gates or Hillary Clinton, but from Yoweri Museveni, Uganda's president, who made an impassioned appeal to investors to come to Africa.

"There are a lot of crocodiles in Uganda. Crocodiles have been eating us since time immemorial. These crocodiles could be eaten and made into handbags. But none of our people had the eyes to see that. That highlights the lack of entrepreneurs on the continent. So please, more entrepreneurs."

After the Celtic Tiger, maybe the Ugandan croc will be the next international success story.
