Lindenstraße: Lindenstraße (literally "Lime Street") is a German television drama series, broadcast by Das Erste.  The first episode aired on 8 December 1985 and since then new episodes have aired weekly.  Its current timeslot on Das Erste is Sundays at 18:50.  The events of the Sunday episode usually take place on the Thursday before the show, based on the TV station's original plan of airing the episodes Thursday night.  Prior of the start of the show, the timeslot was switched to Sunday evening but the Thursday remained the day the events usually take place as the show shall feature the daily life routine of the protagonists on a working day.

Venezuelan parliamentary election, 2015: Parliamentary elections were held in Venezuela on 6 December 2015 to elect the 164 deputies and three indigenous representatives of the National Assembly.  They were the fourth parliamentary elections to take place after the 1999 constitution, which abolished the bicameral system in favour of a unicameral parliament, and the first to take place after the death of President Hugo Chávez.  Despite claims from the opposition of a possible last-minute cancellation, the elections took place as scheduled, with the majority of polls showing the Democratic Unity Roundtable (MUD) holding a wide lead over the ruling United Socialist Party of Venezuela (PSUV) and its wider alliance, the Great Patriotic Pole (GPP).

List of political parties in Angola: The Popular Movement for the Liberation of Angola (MPLA) has ruled Angola since independence in 1975.  From 1975 to 1991, it was the sole legally existing party in a political system inspired by the model then practised by the socialist countries of Eastern Europe.  Since 1991/1992, a multiparty system exists, where the MPLA has been dominant because of the majority it won in the 1992 parliamentary and presidential elections.  In the latter, it failed to obtain the required absolute majority for its candidate, José Eduardo dos Santos, and according to the constitution, a second round would have been necessary.  The outbreak of the Angolan Civil War made this impossible, and José Eduardo dos Santos exercised presidential functions without a legal basis.  For the same reason, the regular parliamentary elections stipulated by the constitution did not take place, and the parliament elected in 1992 remained in place for 16 years.  While large sections of the interior were for years controlled by the armed forces of the rival movement National Union for the Total Independence of Angola (UNITA) under the leadership of Jonas Savimbi, UNITA's elected MPs were a regular part of the parliament, and for some years a government of national unity, led by the MPLA, also included members from the UNITA as well as from the National Liberation Front of Angola (FNLA), the third movement that had fought the independence war against Portuguese colonial rule.
