David Higgins and Seb Coe are at a press conference this morning where they could announce significant changes to the masterplan.

The Olympic Delivery Authority is expected to announce today that it will be re-submitting the Olympic masterplan for the 2012 Games.

ODA chief executive David Higgins and LOCOG chairman Seb Coe will chair a press conference this morning in which the masterplan could show significant changes to the design that won London the bid.

The announcement signals the conclusion of the period of testing and validation of the masterplan for the Olympic Park, the centrepiece of the London 2012 Olympic Games and Paralympic Games. This validation period has been ongoing since London won the bid on July 6 last year. The announcement will allow London 2012 to move on to the next phase in the project.
