AMMAN (AFP) - Fifa presidential contender Prince Ali al Hussein has denounced a possible attempt to breach the election rules and called for an investigation.

"I am concerned that there has been an attempt to breach electoral rules in the Fifa presidential election," the Jordanian prince said in a statement.

"I have written to the Fifa Ad Hoc Electoral Committee informing them of my concerns and asking them to examine the matter."

It comes after the Confederation of African Football (CAF) signed an agreement with the Asian Football Confederation (AFC) to organise tournaments and programmes for technical development.

The AFC is headed by Bahraini Sheikh Salman Ebrahim al Khalifa, who is also running for the top job in world football.

"I have always promoted cross-regional understanding," Prince Ali said.

"However the timing of this MOU between the AFC and the CAF looks like a blatant attempt to engineer a bloc vote."
