Farmers protest party BBB looked set to become one of the largest parties in the Dutch Senate, a first exit poll following regional elections held on Wednesday showed.
Newcomer BoerBurgerBeweging (Farmer-Citizen Movement) was indicated to have won 15 of 75 Senate seats, at a par with the Labour/GreenLeft combination which was also projected at 15 seats.
Prime Minister Mark Rutte's conservative VVD party was expected to drop from 12 to 10.
