Provincial elections were held in the Netherlands on 15 March 2023, on the same day as the water board elections, as well as island council elections in the Caribbean Netherlands.[1][2][3]
The elections resulted in a victory for the Farmer–Citizen Movement, which had been formed three years prior; the BBB won the popular vote and the most seats in all twelve provinces. (It tied for most seats with the People's Party for Freedom and Democracy in North and South Holland, and with GroenLinks in Utrecht.)[4][5][6][7] It was the first time in Dutch history a political party won the popular vote in all twelve provinces.
These elections also indirectly determined the composition of the Senate, for the members of the twelve provincial states, alongside electoral colleges elected on the same day, elected the Senate's 75 members in the Senate election on 30 May, two months after the provincial elections.[8][9]
Elections for the provincial councils of the twelve provinces of the Netherlands are held every four years in March using the D'Hondt method. Voters also have the option to cast a preferential vote. The seats won by a list are first allocated to the candidates who, in preferential votes, have received at least 25% of the number of votes needed for one seat, regardless of their placement on the electoral list. If multiple candidates from a list pass this threshold, their ordering is determined based on the number of votes received. Any remaining seats are allocated to candidates according to their placement on the electoral list.[10] The size of the provincial councils ranges from 39 members for a province with fewer than 400,000 inhabitants to 55 members for a province with more than 2,000,000 inhabitants. As of 2023 there are a total of 572 seats in the provincial councils.
As of 21 December 2022, 49 parties have been registered with the Electoral Council for participation in general elections, which carries over to provincial elections.[11] Parties can also participate in a province by registering their party name in that province instead of nationally.[12] Which parties participate differs per province, with most large parties represented in the House of Representatives participating in all provinces and some local and smaller national parties also participating.
A “-” in the table means that the party in question has not submitted a list of candidates for the 2023 election in that province.
