The man in charge of the legacy of the Olympic Park has been moved to a new job looking at aviation policy by London’s mayor - and replaced in the seat by Boris Johnson himself.

Daniel Moylan was appointed chairman of the London Legacy Development Corporation (LLDC) just over three months ago by Mr Johnson, but it was announced today that he will now spearhead the Mayor’s new aviation policy unit.

Mr Johnson has said he will take on the chairmanship of the LLDC himself.

He said: “Securing the future of the Olympic and Paralympic legacy and building on the regeneration of east London is a matter of huge importance to me personally. It is vital that I continue to be at the forefront of the decision-making, driving forward the huge task of delivery. The chairmanship of the LLDC will enable me to do just that, building on what has already been achieved.

“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.

“Throughout the incredibly busy Olympic and Paralympic Games, Daniel has shown great insight and determination in driving my legacy agenda and I’d like to thank him for his immense contribution.”

Mr Johnson favours a new hub airport to serve London, and is fiercely opposed to any proposals to expand Heathrow Airport.

Mr Moylan said: “I have worked with Boris for two years now to bring London’s pressing need for a new hub airport to the top of the political agenda. The 2012 Games have shown that Britain can deliver major projects better than anyone if it has the will to do so.

“A new hub airport to the east of London would be the greatest legacy we could create for London and the country at large. That is why I have accepted the Mayor’s invitation to put the majority of my time into aviation. The time for action is now and we need to bring the Government round to that view.

“I have had the huge privilege of chairing the Legacy Corporation for the last three months, working with its dedicated staff and getting to know the fantastic, enthusiastic and wonderful people of Stratford and the nearby areas.

“I give up the post with a heavy heart, but knowing that, alongside aviation, the Mayor intends to make this one of the great priorities of his second term and is demonstrating this by taking the chairmanship of the Legacy Corporation himself.”
