Heather Rabbatts, one of the English Football Association's two independent directors, has resigned from FIFA's anti-discrimination task force following Sepp Blatter's re-election as president.
Rabbatts said it was "unacceptable" that so little has been done to reform FIFA and that the latest corruption crisis was "disastrous" for the world governing body's reputation.
Her action follows English FA vice-chairman David Gill rejecting his place on the FIFA executive committee in protest at Blatter's election victory.
Rabbatts had been a member of FIFA's anti-discrimination task force chaired by Jeffrey Webb, the FIFA vice-president from the Cayman Islands who was one of the seven officials arrested in Zurich on corruption charges last week.
