The full value of the London 2012 Olympics and Paralympics can not be judged for up to 10 years, according to Sports Minister Hugh Robertson.
"I do not think the full benefits can be seen until at least three or five or probably 10 years after you have hosted the Games," he said during a speech marking the first anniversary since the Games.
The impact on sport from hosting the Games is "already extraordinary and compelling", he suggested, adding:
"We are the first host nation who has ever increased funding for Olympic and Paralympic athletes - by 11% and 43% for Paralympic athletes for the Games (Rio de Janeiro 2016) after a home Games."
