Treasury asks spending departments to search their budgets for contributions to 拢3.7bn cost of Games

The Treasury has demanded that government departments search their budgets for a contribution to the 2012 Olympic Games, which are rumoured to be facing a 拢1bn shortfall.

A senior Treasury source said: 鈥淲e are scrabbling around at the moment trying to find money for the Olympics. The Treasury is looking for all departments to come up with suggestions for how much they can find to put towards this.鈥

It is unclear how much the Treasury hopes to collect, but there is speculation that the 拢3.7bn in public funds earmarked for the construction of the Olympic park in north-east London is at least 拢1bn short.

Some of the departments have large annual budgets; the ODPM, for instance, has 拢50bn. 黑洞社区 understands that a number of departments have already responded to the Treasury鈥檚 call.

The 拢3.7bn total is made up of 拢2.4bn to build the Olympic park, 拢800m for infrastructure and 拢478m for site acquisition costs. The source said: 鈥淭he only thing the Treasury is confident of is that it will cost much more than it thinks.鈥

A Treasury spokesperson said:

鈥淚t has always been accepted that there are costs associated with the Olympics that would have to be funded outside the lottery and London council tax public sector funding envelope.

鈥淭he government has ensured that there is no shortfall in the current spending period and the issue will be revisited in the 2007 Comprehensive Spending Review."

The news comes as the Treasury reviews the way financial management is carried out in Whitehall, after concerns that government spending lacks transparency.

The review into Whitehall鈥檚 financial management is being led by Mary Keegan, head of the government accounting service, and the Treasury鈥檚 private finance unit. The aim is to replace arcane budgeting methods with the stricter standards of the private sector.

One potential change is to implement a 鈥渮ero-based approach鈥 to budgeting each year. This would mean that a department applying for funds from the Treasury, for a hospital would have to justify every penny during each year of the contract. This means starting annual budgets from scratch.

Under the current 鈥渋ncremental鈥 approach the previous year鈥檚 budget is adjusted for inflation and expected market changes. Departments have to maintain their budgets every year in order to retain funding.

The accounting change under consideration could be particularly useful in assessing the cost of design-and-build projects when capital spending is high.

A source close to the Treasury said: 鈥淯nder the current system, it鈥檚 difficult to do analysis of projects. It might be that they find schemes cost a lot more than they thought.鈥
