One of the seven FIFA officials arrested over corruption allegations has been extradited to the US, say Swiss authorities.

The US formally asked Switzerland to extradite the seven FIFA officials arrested in Zurich in May as part of a US investigation into alleged bribery involving more than $100m within football's governing body.

The seven, who are among 14 people from North and South America charged by US authorities, had been fighting the extradition requests. Those suspected of paying the bribes were allegedly given media, marketing and sponsorship rights for football tournaments in the US and Latin America.

The US is involved because the crimes are alleged to have been agreed and prepared in the US and the bribes were allegedly sent through the US banking system.
