The £1bn Paddington Health Campus fiasco could be referred to the House of Commons’ most powerful select committee, says the National Audit Office.

The scheme, which collapsed in June after one of the health campuses involved pulled out, could be scrutinised by the Public Accounts Committee, which looks at public expenditure.

The scheme is the subject of an independent review to consider “lessons to be learned” by the North West London Strategic Health Authority. However, MPs have been concerned at the limited amount of time for the review, amid fears of a whitewash.

In a letter last month, NAO head Sir John Bourn assured critics of the scheme that the matter would be raised with the committee. He said he was satisfied that the independent review would produce answers.

But he added: “It is fundamental to my role that I draw matters of concern to the Committee of Public Accounts and its chairman. I intend to report to the chairman on our wider perspective of the lessons learned and issues the committee may wish to consider.”
