Computer Weekly has announced the seventh annual UKtech50, our definitive list of the movers and shakers in UK IT - the CIOs, industry executives, public servants and business leaders driving the role of technology in the UK economy.

Our aim was to identify the 50 most influential leaders in UK IT. An expert judging panel representing every aspect of the IT profession helped decide the results, along with a reader vote, to determine who holds the most influence over the future of the UK tech sector in the next 12 months – and the future of IT professionals across the country.

Here is the list of the 50 most influential people in UK IT for the next 12 months:
