"It is completely absurd that established media outlets can publish unconfirmed or incorrect claims citing 'sources'," Ali writes on Facebook.
"I have neither postponed any police questioning nor had any conversation with the police regarding the alleged election fraud," he continues.
According to sources who spoke to Aftonbladet, Ali had rescheduled police questioning to which he had been summoned on more than one occasion.
Mohamed Ali unexpectedly entered parliament through personal votes, and the police are investigating suspected election fraud linked to his personal campaign. However, he has not himself been charged with a crime.
Ali has not been present in parliament since the election. First, he applied for two weeks of leave, and after that he went on sick leave.
Deputy party leader Ida Gabrielsson said on Tuesday that Ali is expected to return to parliament shortly, according to SVT.
He will come as soon as possible, and then he will be included in the work of the Riksdag (the Swedish parliament), she said.
However, according to the Left Party's press service, he will miss Thursday's vote on S leader Magdalena Andersson as prime minister because he is still on sick leave.
