Athletes with a learning disability were banned from taking part after Sydney 2000 after a small number of athletes had competed in the learning disability division who did not have a learning disability.
As a result, the learning disability classification was suspended from the Paralympic Games until a number of conditions could be met.
In June 2007, it was announced that these conditions had not been met. Athletes with a learning disability would not take part in the Beijing Paralympics in 2008.
The decision will be reviewed again this year, and Mencap hope that the ban will be lifted to ensure that athletes have sufficient time to train towards London 2012.
You can support the campaign by writing letters of support to your local MP, by supporting athletes, and by raising awareness of sporting opportunities at all levels for people with a learning disability. Click here to find out more on Mencap's website.
