1.4 Individual government departments and arm's-length bodies are responsible for delivering specific projects. The extent to which their work is delivered through projects varies by department. For example, the Ministry of Defence has the most projects in the Portfolio, followed by the Department of Health and the Ministry of Justice. The Ministry of Defence together with the Department of Energy & Climate Change and the Department for Transport also account for most of the total whole-life cost of the Portfolio (78% - £400 billion) with 57 projects between the three departments (Figure 2).
