Medvedev’s Cabinet also resigned.
In a statement issued by the Russian news agency Tass, Medvedev, a lawyer who has known Putin since they worked together in St Petersburg in the 1990s, linked the unexpected resignations to an overhaul put forward earlier Wednesday by Putin.
Putin proposed amending the Russian Constitution to expand the powers of Parliament and a body called the State Council, which currently carries little weight.
Medvedev said those moves would “introduce significant changes” to “the balance of power” between the executive, the legislature and the judiciary. Putin named him as deputy head of the Kremlin Security Council, a powerful body that includes defence and security officials.
It was not immediately clear whether the resignations signalled a rift at the top of Russia’s hierarchy or were part of a coordinated but as-yet-unclear plan by Putin to reshape the political system.
Putin has a long record of wrong-footing friends and foes, and he has ensured that he has remained the arbiter on all important decisions in Russia since Yeltsin resigned on Dec 31, 1999.
The Constitution limits a president to two consecutive terms, meaning that without a change, Putin would have to step down in 2024.
The last time Putin faced the two-term limit, in 2008, Medvedev was elected president. Putin became prime minister, though he remained the real power in the government, and he returned to the presidency in 2012, when Medvedev became prime minister.
Putin, who has hinted at staying in power beyond 2024, could be planning a similar move, becoming the prime minister at the helm of a newly empowered Parliament, or head of the state council.
