Researchers studying our most successful Games team in more than a century found immigration was a factor in least 24 of the 65 medals won by Team GB.
The analysis of podium places, by British Future, a think tank, found at least 11 gold medals, three silvers and 10 bronzes were won by athletes whose immediate family came to Britain from overseas.

At least 16 medal-winners have family links to Nigeria, including 400m silver medal-winner Christine Ohoruogu, 28, whose parents moved to Britain in 1980 while 23 year-old boxing bronze medal-winner Anthony Ogogo’s father is Nigerian.
"The record-breaking achievements of Team GB athletes have reflected an inclusive and authentic pride in the shared, multi-ethnic society that we are today,” said Sunder Katwala, a director of British Future.

“Then, the popular sprinter McDonald Bailey from Trinidad stood out of the team photo as the only black athlete in a sea of white faces.”
The former general secretary of the Fabian Society told the Independent: “In 2012, Team GB has changed because Britain has changed.
