Dmitry Anatolyevich Medvedev (; born 14 September 1965) is a Russian politician who has been serving as the deputy chairman of the Security Council of Russia since 2020. Medvedev also served as the president of Russia between 2008 and 2012 and as the prime minister of Russia between 2012 and 2020. Medvedev was elected president in the 2008 election. He was regarded as more liberal than his predecessor, Vladimir Putin, who was also appointed prime minister during Medvedev's presidency. Medvedev's top agenda as president was a wide-ranging modernisation programme, aiming at modernising Russia's economy and society, and lessening the country's reliance on oil and gas. During Medvedev's tenure, the New START nuclear arms reduction treaty was signed by Russia and the United States, Russia emerged victorious in the Russo-Georgian War, and recovered from the Great Recession. Medvedev also launched an anti-corruption campaign, despite later being accused of corruption himself. He served a single term in office and was succeeded by Putin following the 2012 presidential election. Medvedev was then appointed by Putin as prime minister. He resigned along with the rest of the government on 15 January 2020 to allow Putin to make sweeping constitutional changes; he was succeeded by Mikhail Mishustin on 16 January 2020. On the same day, Putin appointed Medvedev to the new office of deputy chairman of the Security Council. In the views of some analysts, Medvedev's presidency did seem to promise positive changes, both at home and in ties with the West, signaling "the possibility of a new, more liberal period in Russian politics"; however, he later seemed to adopt increasingly radical positions.
