The anti-immigration PVV remains the biggest party in the latest Peilingwijzer poll of polls but its support is down 3.3%, or five seats, on its January record high.
The poll of polls, an amalgam of four different opinion polls, says the PVV would win between 19% and 22% support if there were a general election tomorrow.
The right-wing Liberal VVD, the majority partner in the current cabinet, has gained in support and would win between 16% and 19% of the votes in an election.
Support for the Socialist party is also down by the equivalent of seven parliamentary seats on its position a year ago. The left-wing greens GroenLinks, however, show a three-seat rise. Dutch opinion polls are usually expressed as a share of the 150 seats in the lower house of parliament, rather than percentages.
There is little shift in the popularity of the other parties, with the Christian Democrats remaining on between 16 and 18 seats, the D66 Liberals on 14 to 18.
Political scientists expect there will be more movement in support once the parties decide who will lead their general election campaigns. In particular, the coalition Labour party is suffering from the poor image of its leader Diederik Samsom, broadcaster Nos said.
