The UKtech50: The top 20

Chris Chant's day job involves introducing cloud computing to Whitehall - a task he sees as being as much about cultural change as technological change. Chant has recently become one of the most vocal supporters of IT reform in Whitehall. He is the voice of discontent about the status quo - the sort of maverick role that Whitehall press officers would never have countenanced in the past. Chant has previously been CIO at the Department for the Environment, Food and Rural Affairs, and at the former Inland Revenue where he led delivery of the online tax self-assessment system.
