A series of reports from Aftonbladet have revealed the presence of cocaine residue on the premises of four out of eight Swedish parliamentary parties, raising concerns about drug use within the highest levels of the country's political system.

The affected parties include the Liberals, Social Democrats, Sweden Democrats, and the Left Party.

The discovery has prompted various reactions from political leaders, with some expressing shock and others proposing stringent measures like drug testing all members of parliament.

The findings have initiated a wave of internal investigations and discussions regarding security, substance policies, and the potential implications for the integrity of Sweden's political institutions.

The Riksdag's security chief has confirmed that the police are aware of the events, and a police report has been filed.

While some party representatives suggest the traces could have been left by visitors, the revelation has nonetheless sparked a broader debate about drug policy and the role of lawmakers in setting an example for national conduct.
