A study commissioned by the DfT has revealed that the procurement process had contained serious flaws.

The report conducted by Centrica also identified failures in transparency and in the process of risk calculation. Despite being aware of failures in following its own guidelines the DfT continued the bidding process.

The report detailed that: “These errors appear to have been caused by factors including inadequate planning and preparation, a complex organisational structure and a weak governance and quality assurance framework.”
