Geert Wilders’ anti-Islam PVV has drawn level with the ruling right-wing Liberal VVD in the latest Peilingwijzer poll of polls but still fails to gather more than 20% support.

Both parties would win between 25 and 29 seats if there were a general election tomorrow, the ranking – an amalgam of four different opinion polls – shows. The PVV have gained three seats while the VVD have lost three.

The poll of polls shows that the benefits felt by the ruling coalition since the MH17 air disaster have now faded away. ‘Voters were impressed by the cabinet’s reaction to the disaster,’ political scientist Tom Louwerse told broadcaster Nos. ‘The VVD was able to benefit from this until the end of September but the impact would appear to have faded.’

The negative impact of Wilders’ anti-Moroccan chanting and the spate of resignations which hit the party afterwards have also worked through, Louwerse said. ‘Islamic State and Islam are now big issues and that is where the PVV has a strong profile,’ he said.

The party showing the greatest variation in support is the CDA. The polls show it would win anywhere from 23 to 14 seats in the 150 seat parliament if there were a general election tomorrow. Louwerse said he was unable to explain the variation because the polling agencies don’t give much information about their polling methods.
