The biggest opinion drop took place in the Centre party, whose leader among others has been criticised for her handling of the Saab crisis and the state owned energy company Vattenfall.
In the opposition, also the Left Party polled below the 4-per cent threshold. In total, the three party opposition coalition got 51,2 per cent of the voters sympathies in the poll, while the government coalition parties only scored 41,8 per cent.
The wild card, the extreme right xenophobic Sweden Democrats attracted five per cent of the voters in the poll, which - if this was an election result - would grant them a place in parliament.
The next general election will be held in September this year.
