Pressure builds on Fifa's Sepp Blatter to stand down

Pressure is building on Sepp Blatter to stand down as president of world football's governing body Fifa - in the wake of the corruption allegations around the organisation.

The Prime Minister David Cameron has joined calls for him to resign.

Visa has become the first major sponsor to warn Fifa that it may review its ties if it fails to introduce urgent reforms.

Blatter held an emergency meeting this morning with representatives from the six confederations including UEFA to discuss the crisis.
