16th Supreme Soviet in 1994. In that year, the Supreme Soviet was replaced by the Oliy Majlis. The third elections for the bicameral 150-member Oliy Majlis, the Legislative Chamber, and the 100-member Senate for five-year terms, were held on 27 December 2009. The second elections were held from December 2004 to January 2005. The Oliy Majlis was unicameral up to 2004. Its size increased from 69 deputies (members) in 1994 to 120 in 2004–05 and currently stands at 150. Karimov's first presidential term was extended to 2000 via a referendum, and he was re-elected in 2000, 2007, and 2015, each time receiving over 90% of the vote. Most international observers refused to participate in the process and did not recognise the results, dismissing them as not meeting basic standards. The 2002 referendum also included a plan for a bicameral parliament consisting of a lower house (the Oliy Majlis) and an upper house (Senate). Members of the lower house are to be "full-time" legislators. Elections for the new bicameral parliament took place on 26 December. Following Islam Karimov's death on 2 September 2016, the Oliy Majlis appointed Prime Minister Shavkat Mirziyoyev as interim president. Although the chairman of the Senate, Nigmatilla Yuldashev, was constitutionally designated as Karimov's successor, Yuldashev proposed that Mirziyoyev take the post of the interim president instead in light of Mirziyoyev's "many years of experience". Mirziyoyev was subsequently elected as the country's second president in the December 2016 presidential election, winning 88.6% of the vote, and was sworn in on 14 December. Deputy Prime Minister Abdulla Aripov replaced him as prime minister. Mirziyoyev removed most of Karimov's officials and urged the government to employ "new, young people who love their country." After a year in office, Mirziyoyev moved away from many of his predecessor's policies. He visited all the Uzbek regions and big cities to get acquainted with the implementation of the projects and reforms which he ordered. Many analysts and Western media compared his rule with Chinese Communist Party leader Deng Xiaoping or Soviet Communist Party general secretary Mikhail Gorbachev. His rule has been quoted as being an "Uzbek Spring". Foreign relations Uzbekistan joined the Commonwealth of Independent States in December 1991. However, it is opposed to reintegration and withdrew from the CIS collective security arrangement in 1999. Since that time, Uzbekistan has participated in the CIS peacekeeping force in Tajikistan and in UN-organized groups to help
