Queen Sofia is suing the Ashley Madison website for "damage to her honor and dignity," ThinkSpain reported.
Ashley Madison used a picture of the queen with slogan, "Now you no longer have to spend the night alone" in one of its advertisements.
The advertising regulatory board, Autocontrol, agrees with the queen that the advertisement should never have been launched and should be removed.
The Ashley Madison dating service is marketing mainly to people who are already in relationships.
