Every year, the CIO50 list ranks the most influential and effective CIOs in the UK.

This year sees the sixth annual CIO50 – and the first time it’s appeared on TechRepublic.

The CIO50 is the only list that allows CIOs to rate their fellow CIOs and provides a fantastic insight into who really are the top-performing tech leaders in the UK.

The full list of 50 CIOs will be unveiled later this year, but to make the list as accurate as possible we want the help of more UK CIOs.

If you are a UK-based CIO working for an end-user organisation – sorry, no tech companies – and want to vote for this year’s CIO50, simply drop me an email at steve dot ranger at techrepublic.com with the names of up to three UK CIOs who you think should make the list, in order of preference.

I’m looking for UK-based CIOs who excel in terms of their leadership ability, delivery and execution, innovation, and influence. The final date for votes to be submitted is Monday 1 October.
