Jenny Wenhammer, a member of the Green Party (Miljöpartiet), made headlines during political week in Almedalen when she and three other protesters tried to gatecrash Reinfeldt's speech.
The quartet, who are members of the feminist organization Femen, screamed "lobbyists go home" before being dragged away. Three of them were fined but Wenhammer escaped as she kept her shirt on.
However, her behaviour earned Wenhammer criticism from members of the Green Party. Now the Greens have gone further and ousted the Swede from their list of parliamentary candidates in southern Sweden where she is based.
"It's not consistent with being an elected representative for the Green Party - or to be a candidate with such a mandate - and at the same time disturb representatives from other parties when they are speaking," the Green Party stated in a press release.
At the time of the incident Wenhammer expressed regret that she had been unable to run barechested onto the stage. The three other women, two from France and one from Spain, were each fined 2,500 kronor ($365) after having been charged with disorderly conduct.
The stunt generated a lot of publicity on social media whilst the incident was widely reported in Swedish newspapers. Wenhammer and her three other Femen protesters were attempting to bring attention to a proposed limestone mine in Ojnareskogen in northern Gotland.
"The aim was to direct us to the person with the most power in Sweden and Almedalen that could have an influence on the mining boom going on now," she told Aftonbladet at the time.
Femen is originally a Ukrainian women's group that applies "sextremism" to draw attention to equality and democracy issues.
