The National Audit Office (NAO) has criticised Government transparency regarding work carried out by the Major Project Authority (MPA) worth £376 billion, while praising improvements carried out.

Of 205 projects under the MPA only 39 had confidence ratings in the red of amber/red, yet the MPA reported this year that only half of the 205 projects had been delivered effectively within budget.

Amyas Morse, head of the NAO, said: “If the new system is to be ‘built to last’, the Major Projects Authority needs to carry out the initial commitments to public reporting and be part of a more fully integrated assurance across government.”
