The British Olympic Association calls on the International Olympic Committee today to completely revamp its ticketing policy
Some 3,000 Olympics tickets from international sports federations were "put back in the pot" last night and sold to the public.
The organisers of the Paralympic Games have been accused of discriminating against the disabled by making wheelchair users book tickets for events via business rate phone lines.
Those trying to book wheelchair tickets or check their availability can only do so by calling an 0844 number costing up to 41p a minute, while able-bodied people can buy their tickets online from organiser Locog without incurring extra costs.
The arrangements have caused outrage among some disabled people who say they have been kept on hold for long periods of time running up large bills before being told there are no seats available.
The London 2012 website has a specific section for disabled people wanting to buy tickets to the Paralympics, which start on Wednesday.
It says: "If you require a wheelchair space, you will be able to purchase one, subject to availability, by calling 0844 847 2012."
According to communications regulator Ofcom, 0844 calls are charged between 1p and 13p per minute for landline customers. Calls from mobile phones are typically charged between 15p and 41p per minute, depending on the network provider.
On its website, Locog says it has created a ticketing process which is "inclusive and accessible".
"It is important to us that people of all abilities can purchase tickets easily," it adds.
Sport fans flocked to the London 2012 website yesterday after 140,000 extra Paralympic tickets went on sale. 40,000 were for sporting events while 100,000 gave access to the Olympic Park. However, the website had none available by the evening.
The number of visitors to the Olympic Park since the Games started has now passed 2 million.
The announcement came as Boris Johnson was presented with some of the hundreds of comments from Londoners backing calls for the park to stay open an extra week after the Paralympics.

With the end of the Games in sight, the demand for the few remaining, precious tickets is growing, with fans queuing overnight to get their hands on them.
One ticket source is the London bases for foreign teams, so we sent Liz Wickham to the Czech Republic's HQ in Islington.
ITV London viewers have been getting in touch, describing their difficulties in trying to buy tickets to see the Games. Liz Wickham went online to see if she could get hold of some Olympic action.
More than two million spectators turned out to watch the first three days of London 2012, organisers said today.
Some 856,000 fans, including the football crowds and a "conservative" estimate of 500,000 for the road race, watched on Saturday, with a further 900,000 turning out on Sunday.
A further 370,000 spectators watched yesterday, meaning attendee rates for the three days were 86%, 92% and 88% respectively.
