Farmers’ party BBB has dropped out of talks to form a provincial government in Utrecht after a proposed seven-party coalition fell apart in less than a day.

The regional informateur, Anne Lize van der Stoel, who had the task of identifying a working government following the provincial elections in March, recommended a combination of seven parties led by the BBB and the right-wing liberal VVD.

But the centre-right coalition, which also included the Christian Democrats, hard-right JA21 the orthodox Protestant SGP and pro-European Volt, failed to get off the ground after the more moderate Christian party CU declined to take part.

The CU said it had not received assurances from JA21 that it would drop the pledge in its manifesto to block any new wind turbines in Utrecht and dismantle existing ones.

Arne Schaddelee, the CU’s deputy leader, said his party felt ‘no comfort’ in going into talks with the other six parties without clarification on the wind turbines issue. The CU said it favoured a coalition led by BBB and GroenLinks, but the two parties said last week that their differences on issues such as climate change and farm buyouts were ‘irreconcilable’.

The BBB emerged from the provincial elections as the largest party in all 12 provinces, but the margin was narrowest in Utrecht, where it edged out GroenLinks by less than half a percentage point. Both parties have seven seats, while the VVD are the next largest with six.

Anton Verleun, chairman of the BBB’s provincial group, told Radio M Utrecht his colleagues were ‘extremely disappointed and angry’ and suggested that the other parties had conspired to exclude the BBB.

‘We had one chance to come to an agreement with GroenLinks and didn’t get the change to talk to other parties. It seems as if we’re being shut out. I have the feeling that a game is being played.’

Assembly members agreed on Monday night to ask GroenLinks and the VVD to appoint new negotiators to try to form a majority coalition for the 49-seat assembly without the BBB.
