Swedish prosecutors have reopened a preliminary investigation into possible election fraud in Borlange, Dalarna, after reports that several hundred voters used pre-marked ballots for Mohamed Abdukardir Ali, a Left Party candidate who unexpectedly led the party’s individual results. The investigation, opened on September 1 and initially closed for lack of evidence, could prompt Sweden’s Election Review Board to order a recount or re-run in the county, which elects 11 members of parliament. The September 13 election gave the centre-left opposition 176 seats, against 173 for the right-wing bloc; Dalarna elected six centre-left and five right-wing representatives. Prosecutor Oskar Edvardsson said new information justified reopening the case, but no suspects have been identified and the investigation remains at an early stage. Ali denied the allegations. A re-run would be unprecedented for a Swedish parliamentary election and would have to occur within three months, while Niklas Bolin of Mid Sweden University said the national balance would be unlikely to change even if the county result did.
