London: Sepp Blatter has been described as a "lame duck president" by his former FIFA colleague Jack Warner. The Trinidadian, a former FIFA vice-president, has urged Blatter to go now rather than wait for the appointment of a successor.

Warner said: "You can't say you are stepping down and then stay for several more months. You can't do that. You can't do that. You will be a lame duck president."

Warner said he has compiled a file of documents that shows "a link between FIFA, its funding and me, the link between FIFA its funding and the United National Congress (UNC) and the People's Partnership government in (Trinidad and Tobago's) general election 2010."
