The British Olympic Association has called on the International Olympic Committee to completely revamp its ticketing policy for future Games.

London 2012 has become the latest Olympics to be plagued by empty seats in sold-out events, leading to criticism of the London Organising Committee of the Olympic Games.

BOA chairman Lord Moynihan insisted this morning it was "time to stop the blame game", urging the IOC to learn from a problem he said had also dogged the previous three Games in Sydney, Athens and Beijing.

It's time to stop the blame game and also to recognise that this is such a major and complex issue. "Moving forwards, this is an issue that I hope the IOC will take a lead on. "This is an opportunity for the IOC to put in place an overall ticketing policy that can be improved at each Games." "This requires huge investment. We're not talking #100 million-#200 million. "The IOC have now got to take the lead and make sure the investment is in place for a state-of-the-art ticketing policy. "It is our view that Locog are working exceptionally hard to try to sort out as many of the challenges associated with ticketing as possible. "It's so important for the host country, the host city, to get this right."
