Many of the systems government use are not really geared up to modern technology and some date back to the 1970s.14 The Cabinet Office told us that government is a difficult environment for digital projects, partly because these previous systems and old data, known as ‘legacy’, can stand in the way of progress.15 Government relies on legacy systems for many important services.16 For example legacy systems are used by the Home Office to manage the UK border and by police forces to access criminal records and share intelligence.17 This means government is often building on top of existing systems with complex operational dependencies.18 This makes it challenging to move off legacy systems to modern replacements.19
