Mette Thiesen

At the 2013 local elections Thiesen was elected a member of the city council in Hillerød Municipality for The Conservative People's Party (Det Konservative Folkeparti).[7] At the 2015 general election she was candidate for the party in North Zealand Constituency without achieving election.[8] On 27 June 2017 her shift from the Conservatives to Nye Borgerlige was announced.[9] Explaining the shift she described on several occasions finding herself in opposition to her former party and its mayor Dorte Meldgaard.[10][11]

At the 2017 local elections Thiesen was re-elected to the city council of Hillerød, this time for Nye Borgerlige, thus becoming the party's first ever and at the time only elected politician.[12][13] At the 2019 general election Thiesen ran as lead candidate in North Zealand and was elected as one of the party's four first ever members of the Danish Parliament. At the 2022 general election she was re-elected for one of the party's now six seats.[14]

On 2 November, TV 2 published a recording from Nye Borgerlige's election party at Christiansborg. The recording displayed a heated argument between two or more persons culminating with one man throwing beer in the face of another.[15] On 7 November, several media reported that the beer-throwing man had been Thiesen's boyfriend, who had violently assaulted an employee in party.[16] The leader of Nye Borgerlige, Pernille Vermund stated that the employee had gone to the casualty department following the incident, where he had been ascertained with swelling and discoloration on the arm caused by the assault, while the boyfriend had been reported to the police.[17]

In a press release, Pernille Vermund wrote that Thiesen had been prohibited from taking her boyfriend to Christiansborg and party events, but had repeatedly defied this. In addition, Vermund explained that in the summer of 2022 Thiesen and her boyfriend had begun "sending intimidating and threatening messages" to the employee, and that Thiesen would not apologise to the employee or take responsibility for messages but in instead wanted the employee dismissed. According to several media, the employee in question had previously been in a relationship with Thiesen.[18][19] In her later resignation post, Thiesen wrote about this, "I do not apologise for anything I have not done, or to someone who has hurt me. I don't want to do that to myself, because then I'll break". On 7 November, Nye Borgerlige's main board (hovedbestyrelse) held a crisis meeting about the case. Mette Thiesen announced the same day that she had left the party as of that day.[20][21]

After the meeting, the party's main board stated that Thiesen would have been expelled from the party if she had not opted out in advance and that this had been the recommendation of the parliamentary group.[22][23][24]

With her defection Thiesen became the fastest parliamentary politician in Danish history to leave the party for which she was elected for office, having left six days after the general election.[3][4]

On 12 January 2023 it was announced that Thiesen had entered into an informal arrangement with Danish People's Party on practical issues regarding parliamentary work and stayed open about joining DF with the party's group chairman Peter Kofod stating, "If Mette Thiesen wants to be a member of the Danish People's Party, she has my number. Then we'll have a talk about it, should it become relevant".[25][26][27][28][29] On 6 February 2023 she officially joined the Danish People's Party.[30][31][32] On 24 June, she was appointed deputy chairman of the DF's parliamentary group.[33]
