American banking giant CitiGroup, has said it has won a court order temporarily blocking the sale of the troubled bank Wachovia to a rival.
CitiGroup accuses Wells Fargo of trying to frustrate its plan to acquire Wachovia's banking operation for $2.2 billion (€1.59bn)
Financial analysts say the underlying battle is over which bank will emerge the stronger from the financial crisis.
Last week, Wachovia announced it was being bought by Wells Fargo.
