Test your CIO knowledge - and win an iPod

They're leaders, influencers, innovators and strategists. They're at the top of the IT tree. And for the first time, silicon.com names them - the UK's top 50 CIOs.

In our exclusive CIO50 special report, we choose the top UK CIOs - and provide in-depth analysis on how to be the best IT chief today.

But how well do you know these IT leaders?

We're running a competition to test your CIO50 knowledge. The prize: an iPod Nano.

Just read the CIO50 profiles and answer these three questions:

1. Which CIO is a motor sport judge?
2. Which CIO is an art collector?
3. Which three CIOs on the CIO50 list are also pilots (planes or helicopters)?

Send your entry to editorial@silicon.com marked 'CIO50 competition' in the subject line no later than 12:00(BST) on Wednesday, 21 June 2007.

(No cash, or alternative prize, is available. The decision of the silicon.com editorial team is final and no correspondence will be entered into.)
