The 2012 Summer Olympic programme features 26 sports and a total of 38 disciplines. The 2012 Paralympic Games programme has 20 sports and 21 disciplines. London's bid featured 28 sports, in line with other recent Summer Olympics, but the IOC voted to drop baseball and softball from the 2012 Games two days after it selected London as the host city. The IOC reinforced its decision to drop both sports during the Turin Games after they lost votes for reconsideration. They will remain Olympic sports, despite being scheduled for the last time at Beijing in 2008.[57] Following the decision to drop the two sports, the IOC held a vote on whether or not to replace them. The sports considered were karate, squash, golf, roller sports, and rugby sevens. Karate and squash were the two final nominees, but neither received enough votes to reach the required two-thirds majority.[58] The IOC has given the approval for the addition of golf and rugby sevens for the 2016 games.[59][60]
The International Olympic Committee executive board met on 13 August 2009 and approved the addition of women's boxing to the programme. The International Boxing Federation has proposed that 40 athletes compete in five different weight classes.[61]
Murad Qureshi, a member of the London Assembly, is pushing for a Twenty20 cricket showcase tournament to be included in London.[62] Twenty20 cricket did originally bid for inclusion in 2012, but was not one of the finalist sports.[63] Netball is being drafted as a possible demonstration sport at the 2012 games. This idea was backed by Prime Minister Gordon Brown, suggesting that it would encourage more girls and young women to play sports.[64] The IOC eliminated demonstration sports following the 1992 Summer Olympics.[65] However, special tournaments have been run for non-Olympic sports during the games, such as the Wushu tournament at the 2008 Summer Olympics.[62] There has been speculation that the London Sevens tournament held at Twickenham as part of the IRB Sevens World Series could be put back to coincide with the Olympics.[66]
