The government G-Cloud project director Chris Chant is set to retire at the end of this month with no replacement yet chosen.

The director has been critical of public sector CIOs, attacking them in a personal blog posted yesterday for their inability to adapt to meet the modernisation requirements of government IT.

A statement provided by the Cabined Office said: "We are very thankful for the years of service and in particular, his recent success with the G-Cloud Programme. Chris leaves Government ICT in a strong position and we wish him all the best in the future."
