Hamburg Eimsbüttel (electoral district): Hamburg Eimsbüttel is one of the 299 single member constituencies used for the German parliament, the Bundestag.  Located in north west Hamburg, the district was created for the 1949 election, the first election in West Germany after World War II.  With the exception of the 1953 election, which was won by the German Party, all elections until 2009, were won by the Social Democratic Party of Germany (SPD).  However at the 2009 election their vote share almost halved and they finished in third place.  As a result, despite a decrease in their vote share, the Christian Democratic Union (CDU) gained the seat for the first time.  The Greens also had their third best electoral district result (after Berlin Friedrichshain-Kreuzberg – Prenzlauer Berg East and Stuttgart I.)  At the 2013 election the Green's vote share halved, with much of their vote being gained by the SPD.  As a result, despite an increase in his vote shate, the incumbent member of the Bundestag, Rüdiger Kruse of the CDU, lost to the SPD candidate Niels Annen, who had previously represented the district from 2005 to 2009.

Sudeten German Party: The Sudeten German Party (German: "Sudetendeutsche Partei" , SdP, Czech: "Sudetoněmecká strana" ) was created by Konrad Henlein under the name "Sudetendeutsche Heimatfront" ("Front of Sudeten German Homeland") on October 1, 1933, some months after the state of Czechoslovakia had outlawed the German National Socialist Workers' Party ("Deutsche Nationalsozialistische Arbeiterpartei", DNSAP).  In April 1935, the party was renamed "Sudetendeutsche Partei" following a mandatory demand of the Czechoslovak government.  The name was officially changed to Sudeten German and Carpathian German Party ("Sudetendeutsche und Karpatendeutsche Partei") in November 1935.

Lesotho People's Congress: The Lesotho People's Congress is a political party in Lesotho.  It was formed as a split from the ruling Lesotho Congress for Democracy (LCD) by that party's Lesiba faction after Deputy Prime Minister Kelebone Maope resigned from the government in September 2001, and it was registered on October 8, 2001.  Maope became the leader of the LPC; another leading member of the LCD, Shakhane Mokhehle, also became a leading member of the LPC.  It gained 27 seats in the National Assembly through defections from the LCD.  The new party closely identified itself with former prime minister Ntsu Mokhehle (brother of Shakhane Mokhehle), the founder of the LCD, and used an image of his head as its party symbol.  The LCD sought to prevent the LPC from using his head as its symbol, but on December 6 the High Court ruled in favor of the LPC.  In the parliamentary election for the National Assembly held on 25 May 2002, the party won 5.8% of popular votes and 5 out of 120 seats.  Maope was the only LPC candidate to win a constituency, but the party won four other seats through proportional representation.  Maope and Shakhane Mokhehle did not include themselves on the party's list of candidates for proportional representation, expecting to win constituencies, but Mokhehle lost his constituency by nine votes, and therefore did not get a seat in the National Assembly.

However at the 2009 election a drop in their vote share saw them lose the seat.  As a result, despite a decrease in the party's vote share, Jürgen Klimke, the Christian Democratic Union (CDU) candidate gained the seat for the first time.  Klimke did not contest the constituency at the 2013 election and the CDU candidate Frank Schira lost to the current SPD representative Aydan Özoğuz.
