The changes, by the Department for Culture, Media and Sport (DCMS), are designed to ensure existing advertising and trading, ticket touting and traffic management measures introduced by the 2006 Act are able to be properly implemented.

Hugh Robertson (pictured), Minister for Sport and the Olympics, said: "The London Olympic and Paralympic Games Act put legislative measures in place to ensure a smooth and effective running of the Games.

"This bill makes a small number of technical changes to the existing measures to enable us to deliver the Government's commitments to London 2012."

The bill's provisions would require the Olympic Delivery Authority (ODA) to hold goods seized during the Games for breaches of the advertising and trading regulations and increase the maximum penalty for the illegal selling of Games tickets from £5,000 to £20,000.

There are also changes to the procedures for making advertising and trading regulations which allow amendments to be made quickly if required such as if there is an emergency change of venue during the Games.

Regarding the London roads during the Games, the changes to the bill will enable the ODA and traffic authorities to make temporary traffic regulation orders at short notice and traffic authorities to make temporary notices for immediate changes to traffic specifically for Games traffic management purposes.

The traffic authorities will be able to make special event traffic orders involving road closures and other types of traffic restrictions for Games events, while local traffic authorities will have powers to enforce moving traffic contraventions on the Olympic Route Network and other affected roads.

The ODA will now also be allowed to set the penalty charge levels for moving traffic contraventions of Games–related traffic orders, subject to the Secretary of State's approval.

Examples of moving traffic contraventions of Games related traffic orders could be unauthorised vehicles entering a Games Lane on the Olympic Route Network during the lane's operational hours, a vehicle going the wrong way up a one way street or a car making a turn where there is a "no right turn except buses" restriction.
