The Queen and Philip met Prime Minister David Cameron, Health Secretary Jeremy Hunt - formerly Culture Secretary - and other senior figures who made the Games possible, including Lord Coe, former chair of London 2012, in the Palace's 18th Century Room.
I think people will look back and just think, 'what an incredible summer' - success after success, medal after medal and the whole country putting on its very best face for the world.
What matters now is that we maximise the momentum and the legacy following the Olympics and Paralympics.
We had a cabinet meeting about that today and Seb Coe was there, and we were talking about the physical legacy of East London, the important economic benefits we want, there's the sporting legacy carried through to Rio and school sport, there's also the legacy in terms of attitude to disabilities, which I think is a real chance of a step change in our country.
