"deals which could be worth up to £100m"
Is it me, or is the UK Gov making it rain money ?
And on IT projects, no less. Deals worth £100 million ? Don't worry, by the time the project is finished, it will have cost £500 million and still won't work properly.
And kill off bespoke systems ? Impossible. Everything government is a bespoke system.
Unless you want to replace everything with Excel. Which, actually, just might - no, no. Not gonna finish that phrase.
