ZURICH (AFP, REUTERS) - Fifa on Thursday banned former US football official Chuck Blazer for life over his involvement in corruption scandals.

"Mr Blazer committed many and various acts of misconduct continuously and repeatedly during his time as an official in different high-ranking and influential positions at Fifa and Concacaf," said a statement announcing the ban from all football-related activities.

Blazer, 70, has given evidence to the US authorities investigating football corruption and is gravely ill in a New York hospital suffering from cancer.

Fifa's ethics committee says the decision was taken on the basis of investigations in response to report of the Concacaf integrity committee and facts presented by the US Attorney's Office for the Eastern District of New York.

It added that Blazer was a key player in schemes involving the offer, acceptance, payment and receipt of undisclosed and illegal payments, bribes and kickbacks as well as other money-making schemes.
