The government proposes that all parties must declare any donation of more than SEK 22,000 (the equivalent of a modest monthly salary).
So far there are only voluntary guidelines on where parties get their money from. But now the leading government party, the Moderates, has suddenly changed course and accepted a possible change.
"The parties have felt that it's a problem, to be challenged on this all the time" says Justice Minister Beatrice Ask, herself of the Moderate Party.
The new law would come into force on the 1st of April 2014. The Sweden Democrat party is the only political party opposed to naming donors, saying this could put their supporters' safety in danger.
