The International Football Federation has re-elected Switzerland's Sepp Blatter to another four-year term as president. He ran unopposed.

The 71-year-old Blatter was approved by the 207 associations present at the FIFA Congress in Zurich Thursday. He will remain in charge of FIFA until 2011.

Blatter was first elected FIFA president in 1998 after a bitter campaign against former European Football Union head Lennart Johansson. He was re-elected four years later in Seoul, South Korea.

Blatter's second term lasted for five years rather than the usual four, when FIFA decided not to end the president's term of office in the same year as the World Cup finals in Germany.

He first joined the world governing body in 1975 and was FIFA's general secretary from 1981 until 1998.
