The Dutch social democratic party PvdA is the big winner of the European elections in the Netherlands, according to an exit poll by public broadcaster NOS.

Turnout was over 42%, the highest since 1989, the exit poll shows.

The poll gives the PvdA, led by Frans Timmermans, five seats in the European parliament and puts the VVD Liberals and Christian Democrats both on four seats. New party Forum voor Democratie wins three seats in the poll, alongside the left-wing green party GroenLinks.

Not going to stay up all night monitoring election results etc, but looks like a surprisingly good night for Dutch PvdA (Labour Party, previously in a death spiral), with a solid performance from Rutte’s VVD.

The result will be seen as a disappointment for the pro-Nexit Forum, which had been forecast as a potential winner. The anti-European PVV is also set to see its support slashed from four to just one seat, according to the Ipsos poll.

In total, just 15% of Dutch voters have voted for pro-Nexit parties and support for Eurosceptic parties, including the Socialists, is down from 23% to just over 19%.

‘Euroskeptisch/kritisch’ (FvD+PVV+SP) van 22,9% (2014) naar 19,2% (exit poll)

‘Euroseptisch/kritisch’ (FvD+PVV+SP+PvdD+CU-SGP) van 34,8% (2014) naar 30,5% (exit poll) — Tom Louwerse (@tomlouwerse) May 23, 2019

NOS commentator Ron Frensen said that D66, which has a strong pro-EU message, has been squeezed between the ‘Frans Timmermans effect’ and the fighting on the right. Timmermans is also the social democratic parties’ candidate for president of the European Commission.

PvdA leader Lodewijk Asscher said the exit poll prediction is ‘bizarre’. The PvdA has seen its support plummet in recent years but, Frensen said, the party should not count its blessings. Research, he said, shows that 50% of people who voted for the party on Thursday did so because of Timmermans.

Forum spokesman Derk Jan Eppink said the party had expected such a result. ‘I am always very careful with polls and the official results is not until Sunday so we hope for an extra seat,’ he said. ‘Nevertheless, with three seats we can mean something in the European parliament.’

Support for Forum is down from 15% in the provincial elections in March, when the party was the biggest ahead of the VVD, to 11%.

The Netherlands has 26 seats in the European parliament.
