When the buildings are finished I'm sure they'll leave a lasting image in the memories of people right across the world. But the real legacy of the 2012 Games won't be found in buildings or in memories.
Across East London and the rest of the UK there will be lasting change in local communities. World class sporting competition and training venues are being built all over the country. Local areas are being given a new future with jobs and opportunities for all of us.
The lasting positive impact of the Games will be the regeneration and rejuvenation of lost areas and communities. When I go out to talk to local people they tell me they are excited to hear about derelict industrial sites being flattened and turned into green living space, where all members of the community can come and spend quality time together.
For me, the real Olympic legacy is ensuring the future prosperity and sustainability of the Olympic Park and all of East London. That means giving buildings and facilities back to local areas for residential housing; making sporting venues open to public use; and helping local people to benefit directly from the education, training and employment opportunities created during and after the Games.
