Leonie Vestering

She participated in the 2015 provincial election in Flevoland as the Party for the Animals's lijsttrekker.[11] Vestering won a seat in the States of Flevoland and was sworn in in March 2015 as caucus leader. There, she raised concerns about hunting geese.[12] She also filed a criminal complaint for sex with animals after television program Rambam had shown how a zoo keeper was masturbating a dolphin at Dolfinarium Harderwijk. The public prosecutor's office decided not to prosecute, calling it part of an animal breeding program.[13] Vestering subsequently argued for prohibiting shows involving dolphins.[5] She was 23rd on the PvdD's party list for the 2017 general election, received 591 votes, and was not elected.[14]

Vestering became a member of the Almere municipal council and the caucus leader of the Party for the Animals after appearing first on the party list during the 2018 municipal election.[15][16] She was re-elected to the States of Flevoland the following year, again as the party's lijsttrekker.[17] Vestering filed another criminal complaint in the summer of 2019 against Staatsbosbeheer, when about 150 horses in the nature reserve Oostvaardersplassen were held in a field without shade.[18] She had also been the 18th candidate of the Party for the Animals in that year's European Parliament election, supporting a Dutch withdrawal from the European Union.[19] She became a project coordinator of her party's caucus in the House of Representatives in 2020.[4]

Vestering ran for member of parliament (MP) again in the 2021 general election, being placed third on the PvdD's party list.[20] She stopped as caucus leader in the States of Flevoland and the Almere council in December 2020 after the list had been announced, and she resigned from both political bodies the following month.[16][1][21] Vestering was elected with 6,992 preference votes as one of six Party for the Animals members of parliament, and she was sworn into office on 31 March.[22] In the House, she is a member of the Committee for Agriculture, Nature and Food Quality, and she is her party's spokesperson for cattle farming, agriculture, zoonoses, the human impact on the nitrogen cycle, the Netherlands Food and Consumer Product Safety Authority, pesticides, animal rights, food, nature, biodiversity, and wild animals.[23][24]

In May 2021, she filed an amendment to the Animal Act, which was passed by both houses of parliament and says that animals should be able to show their natural behavior when in captivity.[25] Vestering clarified that her amendment would mainly regulate farm animals after concerns that it would have large effects on keeping pets.[26] A legal review requested by the cabinet concluded that its language was too vague and that such a major reform of the agricultural sector would not be achievable within a year. Minister of Agriculture, Nature and Food Quality Piet Adema subsequently announced in late 2022 that its implementation would be postponed to 2024. Furthermore, he planned to draft a covenant with the sector and nature conservation organizations in the meantime and to send it to parliament as a replacement of the amendment. Vestering criticized those steps, saying that the parliament's decision was ignored in favor of industry self-regulation.[27] Vestering also commented on the future of farming when the cabinet set goals to significantly reduce reactive nitrogen emissions, of which the sector is a major contributor, following a decision by the Council of State on the issue. She said that many farmers would have to seek a different profession and that livestock farming in the Netherlands would end, a development she lauded.[28]

Vestering went on sick leave starting 9 May and was temporarily replaced by Eva Akerboom.[29] In a statement, Vestering said her leave was on the advice of a physician based on her working conditions. She mentioned she had discovered the importance of good health following a life-threatening illness the year before after having been infected by a flesh-eating bacteria, from which she had recovered well.[30]
