Disgraced US football official Chuck Blazer has died at the age of 72, his lawyers say.
Blazer, who was banned from all football activities for life in 2015, had been suffering from cancer.
In 2013 he pleaded guilty to bribery, money laundering and tax evasion but agreed to help investigators expose corruption in Fifa.
A larger-than-life character, he was ex-boss of Concacaf, North and Central American football’s governing body.
His information led to charges against 14 other current or former Fifa officials, and contributed to the downfall of Sepp Blatter, the organisation’s president.
