Boris Johnson is to take personal charge of the future of the Olympic Park - becoming the third boss of the unsettled legacy agency this year.
Daniel Moylan, who served just three months as chair of the London Legacy Development Corporation, will depart to run the mayor’s commission on aviation policy.
The mayor is expected to appoint an LLDC vice chair with his chief of staff Sir Eddie Lister and Neale Coleman - his trusted Olympic advisor - thought to be the frontrunners.
City Hall dismissed claimed that there was a disagreement about the future of the £230m Olympic media centre.
The mayor has announced it is to become the iCity “technology hub” but sources have claimed Moylan wanted to demolish the structure and build houses on the site.
Boris Johnson said: “Daniel Moylan is a gifted politician with a superb brain. I’ve asked Daniel to take on one of the most important challenges of my second term, the vital task of driving our aviation policy. London is the heartbeat of the UK’s economy. We must remain competitive, and to do that we need a coherent aviation strategy for 21st century London. Daniel Moylan will help me deliver that.”
Next month the LLDC will decide on the future of the Olympic stadium with West Ham favourites among the four bidders which include proposals from Leyton Orient, an F1 consortium and a business school.
The LLDC is tasked with the £292m transformation of the Olympic Park which will not fully re-open for almost two years.
Transformation work includes building new bridges and roads and converting venues such as the aquatics centre and the “velopark”.
Margaret Ford departed unexpectedly as LLDC chair in the spring and was replaced by Moylan in one of the mayor first post-re-election appointments. Baroness Ford’s chief executive Andy Altman departed soon after and Denis Hone, who ran the Olympic Delivery Authority, is interim CEO.
