Question: Which political party did the son of Lev Sedov become the leader of?

<P0-S0> Lev Lvovich Sedov (Russian: Лев Львович Седов , also known as Leon Sedov; 24 February 1906 – 16 February 1938) was the son of the Russian Communist leader Leon Trotsky and his second wife Natalia Sedova. <P0-S1>  He was born when his father was in prison facing life imprisonment for having participated in the Revolution of 1905. <SEP> <P1-S0> Leon Trotsky ( ;; also transliterated "Lyev", "Trotski", "Trotskij", "Trockij" and "Trotzky". <P1-S1>  born Lev Davidovich Bronstein; 7 November 1879 – 21 August 1940) was a Marxist revolutionary, theorist, and Soviet politician. <P1-S2>  Initially supporting the Menshevik Internationalists faction within the Russian Social Democratic Labour Party, he joined the Bolsheviks ("majority") just before the 1917 October Revolution, immediately becoming a leader within the Communist Party. <P1-S3>  He would go on to become one of the seven members of the first Politburo, founded in 1917 to manage the Bolshevik Revolution. <P1-S4>  During the early days of the Russian Soviet Federative Socialist Republic (RSFSR) and the Soviet Union, he served first as People's Commissar for Foreign Affairs and later as the founder and commander of the Red Army, with the title of People's Commissar of Military and Naval Affairs. <P1-S5>  He became a major figure in the Bolshevik victory in the Russian Civil War (1918–1923). <SEP> <P2-S0> The Aboriginal Peoples Party of Canada (APP) is a Canadian political party that was founded in 2005. <P2-S1>  The party was conceived by University of Lethbridge student Myron Wolf Child. <P2-S2>  It held its founding meeting on August 21, 2005, in St. Albert, Alberta. <P2-S3>  The APP was headed by interim leader Bill Montour, a former Chief of the Six Nations Reserve in Ontario. <P2-S4>  In October 2005, the party had 122 confirmed members, just less than half the number needed to register as an official party in Canada. <P2-S5>  In late October 2005, the APP sought to unite with the First Peoples National Party of Canada which also had fewer than the number of confirmed members needed to become a registered political party. <P2-S6>  The First Peoples National Party of Canada became an eligible political party on December 6, 2005. <P2-S7>  Whether or not this was accomplished through a merger with the APP is unclear. <P2-S8>  If this is the case, the APP no longer exists, but, as one of the stipulations of a possible merger was that a name for the new party would be determined at the party's first convention, it is possible that the name Aboriginal Peoples Party of Canada will come into usage again. <SEP> <P3-S0> Oyun-Erdene Luvsannamsrai (Mongolian: Лувсаннамсрайн Оюун-Эрдэнэ ) is one of the young political leaders of Mongolia. <P3-S1>  His career was started as the Head of the Secretariat of the Governor of Berkh, Khentii, his hometown when he was only 21 years old. <P3-S2>  Then he was recruited by World Vision Mongolia as the team leader of the Area Development Program (ADP) in Khentii province. <P3-S3>  Eventually he was promoted to become the Zonal Director of the organization. <P3-S4>  Since 2009 he has held senior leadership positions such as the Head of the Secretariat of the Governor, the Secretary and acting Secretary General of the Mongolian People's Party (MPP), the oldest political party of Mongolia. <P3-S5>  Between 2010-2014 he served as the President of the Social Democracy Mongolian Youth Federation, the largest political youth organization of Mongolia. <P3-S6>  He is considered as one of the major leaders of the Party as he led the Mongolian People's Party reform to become a modern political party. <P3-S7>  He initiated the “Development Agenda-6” Party platform in 2009 and stood firm on his position to remove the word “revolutionary” from the Mongolian People's Revolutionary Party's name.
