Mette Thiesen

In November she left Nye Borgerlige due to personal issues consequently becoming the fastest politician in Danish history to leave the party one was elected for, having left six days after her re-election in the 2022 general election.

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. 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 Thiensen announced the same day that she had left the party as of that day and wrote, among other things:

In January 2019, Loubani filed a lawsuit against Thiesen for the statements. On 13 December 2019, Thiesen was convicted in the Copenhagen District Court for defaming Loubani by calling him a "terrorist sympathizer". In this connection, Thiesen had to pay compensation of DKK 15,000 to Loubani as well as the costs of the case. Thiesen was acquitted of punishment, as no proceedings were brought within six months of the statements.

On 19 April 2018, Thiesen wrote a post on her Facebook profile with the heading "Terrorist sympathizer used by the Danish Broadcasting Corporation" about the fitness instructor Mahmoud Loubani. In connection with the comments, Thiesen further referred to Loubani as "a person who laughs at people who receive threats".

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). At the 2015 general election she was candidate for the party in North Zealand Constituency without achieving election. On 27 June 2017 her shift from the Conservatives to Nye Borgerlige was announced. Explaining the shift she described on several occasions finding herself in opposition to her former party and its mayor Dorte Meldgaard and stated among other things:

At the 2022 general election she was re-elected as one of the party's now six seats along the three previously mentioned as well as Mikkel Bjørn Sørensen and Kim Edberg Andersen.
