Computer Weekly has announced the 13th annual UKtech50, our definitive list of the movers and shakers in UK technology – the CIOs, industry executives, public servants and business leaders driving the role of technology in the UK economy.

This year, congratulations go, for the first time jointly, to Michelle Donelan and Chloe Smith, secretary of state for science, innovation and technology at the Department for Science, Innovation and Technology (DSIT), who have been named the most influential person(s) in UK technology in 2023.

The role of secretary of state for science, innovation and technology is normally held by Donelan, but as she is currently on maternity leave, Smith has temporarily stepped into the role.

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 to decide the results, along with a reader vote, to determine who holds the most influence over the future of the UK tech sector – and of IT professionals across the country.

The past year has brought new and different types of challenges, and leaders in all parts of the tech industry – from startups to government – have shown incredible spirit, drive and determination to ensure the industry and its people continue to thrive.

The judges’ selection of the top 50 was influenced by several important tech trends – not least the importance of technology in a challenging economic climate. The list reflects the growing influence of sustainability and ethics in the IT sector, as the digital revolution continues to transform the way we all live and work. Judges were keen to promote diversity in the tech community, in terms of gender, ethnicity, geography, industry sector and company size.

Judging was particularly tough this year, not only due to a record number of nominations, but due to the quality of nominees, who have all shown resilience and strength during a challenging time.

Our thanks to the team at Nash Squared for their support with this year's UKtech50.
