The Swedish constitution of 1974 allows the Prime Minister of Sweden to appoint one of the Ministers in the cabinet as Deputy Prime Minister ("biträdande statsminister", also unofficially known as "vice statsminister", "Vice Prime Minister"), in case the Prime Minister for some reason is prevented from performing his or her duties.
 However, if a Deputy Prime Minister has not been appointed, the Minister in the cabinet who has served the longest time (and if there are several with equal experience the one who is oldest) takes over as head of government.
 Note that the person acting as Prime Minister does not do so on a permanent basis: if a Prime Minister dies, resigns or loses a vote of confidence in the Riksdag, the Speaker of the Riksdag will then confer with the parties of the Riksdag and propose a new Prime Minister, who must be tolerated by a majority of the Riksdag.
 If the Prime Minister has resigned or lost a vote of confidence, he or she will remain the head of a government "ad interim" until the new Prime Minister assumes his or her office.
 The only case where the governmental line of succession becomes relevant is when the Prime Minister dies (upon which the person next in the line of succession serves as the head of a government "ad interim") or when the Prime Minister is on leave or for any other reason incapable of serving, but still remains in office.
 This might be compared to the Presidential line of succession in the United States, where the person next in line assumes the Presidency throughout the remainder of the term if the President dies, resigns or is impeached.

 One of the country's top rap artists in the 1990s and the early 2000s, his career has been waning ever since his partner, Ivan Glavchev (Vanko 1), was sentenced in 2003 to 12 years in prison for running an organization that exported Bulgarian prostitutes, including minors, to France, Spain, Belgium and Italy.
 He openly supported Bulgaria's last socialist-led government, whose decision to appoint a media tycoon known for his links to organized crime as head of the national security agency sparked nationwide protests against the Oresharski cabinet.
 He also provoked indignation by calling Bulgaria's former Finance Minister, Simeon Dyankov, "Jewish scum" in 2013.
