		done enough to stop Mr Jodenius from entering the Social Democratic Party's internal computer network. Also, Mr 
		Jakobsson admitted that he had known about the computer intrusions since March of this year. Furthermore, Niki 
		Westerberg, press secretary for the Liberal Party, has taken a leave of absence due to a police investigation of 
		her participation in the incident. According to Swedish Radio News, five Liberal party members have been questioned 
		so far by the police, and more are expected to be questioned about the incident.]]></content:encoded>
