London Olympics projected to be $600 mn under budget

Savings came from a drop in security,transport and construction costs for the Olympics and Paralympics.

As a result of those savings and the unused part of the contingency budget,480 million ($770 million) is left unspent.

The government says this will cover “risks” linked to the revamping of the Olympic Park.

Olympics minister Hugh Robertson says “it is a significant achievement to deliver this large and complex program on time and under budget.”
