England's mooted bid for the 2018 World Cup faces problems with the BBC planning to broadcast a programme investigating senior Fifa figures.

Panorama has sent letters to the Fifa president, Sepp Blatter, general secretary, Jerome Valcke, and executive committee members, Jack Warner and Chuck Blazer, asking them to answer a number of claims.

Panorama says it is examining whether England can expect "fair play" from Fifa in the bidding for the 2018 finals, claims The Independent.

The programme is due to be screened on 29 October, in the middle of the Fifa executive committee meeting in Zurich that is expected to agree to end the rotation of World Cups between continents.
