Additional information about gender quotas
Netherlands
In addition to formal regulations on gender quotas, some parties have initiated other types of measures, such as agreements between various intra-party structures or territorial organizations on the number of women candidates to be selected for nomination. In 2004, the Christian Union adopted a resolution which called national and sub-national party boards and committees to ensure that at least one in every three candidates are women (Stockholm University & International IDEA 2009)
"The 2021 elections returned an even more fragmented House of Representatives than the previous legislature: 17 parties, up from 13 in the previous legislature, entered the 150-member House of Representatives. Only four parties took more than 15 seats." (IPU)
