Visitors discovered the swastika on December 17th. The next day, a woman from the group wrote an upset email to Prime Minister Fredrik Reinfeldt.
"Several of my acquaintances survived the horrors of the Second World War. I think it is unpleasant and upsetting that this type of graffiti has not been removed," the woman wrote.
In a response, Siri Steijer of the Prime Minister's Office said she had "contacted those in charge of caring for the premises at Parliament and they promised to find the symbol and to remove it."
However, reporters from Dagens Nyheter who visited Parliament on Tuesday noticed that the swastika, which is about five centimetres tall, was still there, alongside other engravings made by visitors.
The swastika will be removed Wednesday, said Lennart Gustafsson, head of the Parliament service department.
