Sepp Blatter confirmed onTuesday that should he be re-elected to a fourth term at the head of soccer's world governing body, FIFA, it would be his final spell in charge.

Blatter, 75, announced his intentions at a UEFA Congress. The Swiss has been in the job for 13 years and confirmed the June 1 vote in Zurich would be his final bid.

It had once been thought that Blatter would go unchallenged before stepping aside for current UEFA boss Michel Platini in four years. But he will be challenged for the job by Asian football chief Mohamad Bin Hammam, who has adopted an anti-corruption stance.
