After elections the largest party gets the initiative to form a coalition, where the number 1 becomes the Prime Minister and ideally you want to have more then 50% of the seats in the parliament, although that isn't required. Our current Cabinet contains 2 parties, supported by a 3rd. That in most cases give >50% support.
That is fascinating. Thank you for the insight.
It is even possible to get on the list on your own (without a party). In that way the person gets a list number instead of a party name. Another thing is that after voting often remaining seats are left, which are given to the parties depending on the remaining unfilled votes. Sometimes 2 parties cooperate and link their lists in such way that one of the two parties would get the seat instead of one of the larger parties.
This type of election is for the Parliament and Cabinet. For the Senate we choose indirectly through voting for the province council. They often contain parties that are not in the Parliament and can give sometimes interesting situations (the Cabinet needs a majority in the Senate to pass a law or plans). We had the elections for the provinces recently and the Cabinet wasn't able to get a majority with the ruling parties. Despite the fact that they got a vote from a specific party from one of the provinces about a very controversial (for that province) agreement between the Netherlands and Belgium. In the end they also had to make agreements with a very conservative right-winged Christian party to get some things passed through the Senate (where a large part of the country got a WTF? moment).
