The immediate effects of having the Sweden Democrats in parliament are dire. With neither the opposition nor the returned cabinet in a majority of its own, the newcomers are in a fine position to create parliamentary mayhem. The other parties declared them political pariahs years ago, so the Sweden Democrats may have gained entry to the Riksdag, but they will not be given any direct influence, access to committees or any other rewards. This will of course further reinforce the Sweden Democrats' self imposed image of a victimised movement held back by a conspiracy in the media.
