Fifa president Sepp Blatter has been admitted to hospital for "stress". His spokesman Klaus Stoehlker told AFP the head of the football organisation was under medical evaluation after falling ill as a result of the pressure he has faced in recent weeks.

Sources told the BBC that the 79-year-old will be treated until 17 November. After being re-elected Fifa president for his fifth term in May, Blatter was forced to step down when world football's governing body was hit with corruption allegations. In October, Blatter and Uefa president Michel Platini were suspended for 90 days each by Fifa's ethics committee, as Swiss authorities conduct a criminal investigation into the allegations.

Before his suspension, Blatter said he would step down as Fifa president in February 2016, when the organisation elects a new president.
