Olympics Due To Be Under Budget
The London games will come in £476m under budget.
New figures show not all the £9.3 billion pounds set aside for the games will be needed.
This means an extra £19 million has been moved from within the cash allocated for the Olympics to bolster crowd control and public information for the London 2012 Games.
The success of the Queen's Diamond Jubilee, despite the bad weather, plus the on-going torch relay has alerted organisers to the fact that more stewards and crowd flow measures may be needed.
Olympics minister Hugh Robertson said:
"We have only very recently become aware of the scope of the demand for the Olympic Games."
The money will be used to improve crowd management and public information in central London as well as what organisers describe as the last mile. This is plans covering the distance between transport hubs and Games venues.
No figures on how many more stewards would be needed have been released.
Mr Robertson said: "We know exactly how many tickets have been sold and roughly how many people should be in London. Absolutely nobody knows how many people are going to turn up.
"London this summer is going to be the place to have a party. It is a great national event."
