A corrupt Fifa official worked undercover for investigators for 18 months while on the governing body’s executive committee, it has emerged.
Chuck Blazer, 70, struck a deal with prosecutors in the United States after pleading guilty to charges of bribery, money laundering and tax evasion.
Details of that agreement have been revealed after a judge agreed to a request by five media groups.
The document shows Blazer was secretly co-operating from December 2011.
The American was on Fifa’s executive committee from 1997-2013.
