Minister Magdalena Andersson (Social Democrat) is sceptical the new government can achieve its aim of renegotiating Greece's massive debt.
"The Eurozone has made a loan in euros, and if the Greeks aren't using that currency it'll be hard for them to pay it back," she says to SVT Agenda.
The new Greek government is led by the rising Syriza party, which won a surprising landslide. Syriza is significantly more left-wing than the Social Democrats and is allied with the farthest left-wing group in the EU parliament.
The Swedish Left Party is also in this group. Their leader, Jonas Sjöstedt, says to SVT, from Athens, Greece should be allowed to write of some of its debt.
Syriza was elected on a promise to end the cutbacks made by the previous centre left-centre right government.
