Hovedutfordreren ved presidentvalget i Afghanistan, Abdullah Abdullah, krever en granskning av FN og Kai Eides rolle under og etter valget. Abdullah viser til opplysninger om at Kai Eide har tatt president Hamid Karzais parti og feid bevis på valgsvindel under teppet.
Abdullah sier Eides policy har skadet FNs standing blant afghanere.
But most of the allegations of fraud are against the president and his supporters.
EU election observers have said that about 1.5m votes – about a quarter of all ballots – cast in August’s presidential vote could be fraudulent.
They say that 1.1m votes cast for Mr Karzai are suspicious.
Investigations into voter fraud are ongoing and an official announcement about the result is not expected until next week.
Mr Karzai could still be forced into a run-off election, and his challenger would be Dr Abdullah.
