The Olympic Delivery Authority (ODA) is in the process of restructuring. A source close to the ODA said it was “tweaking roles and responsibilities” and that the changes are expected to be finalised in two months.

It is understood that the changes are being made as the Olympic programme moves out of the planning phase and into construction and delivery, and develops a greater emphasis on legacy. CLM, the Olympic delivery partner, is expected to restructure in line with the ODA.

News of the changes comes amid growing speculation that a senior ODA figure is set to leave. This has been denied by the ODA.

Last week the ODA signed a memorandum of understanding with Sir Robert McAlpine on the main stadium, but no price has been agreed.
