Moscow, Russia (CNN) The entire Russian government is resigning, Prime Minister Dmitry Medvedev announced Wednesday, after Vladimir Putin proposed sweeping reforms that could extend his decades-long grip on power beyond the end of his presidency.

Putin thanked members of the government for their work but added that "not everything worked out." Putin added that in the near future he would meet with each member of the cabinet. The mass resignation includes Medvedev.

The surprise announcement came after Putin proposed constitutional amendments that would strengthen the powers of the prime minister and parliament at the expense of the presidency.

Taking power from the presidency and handing it to parliament could signal a power shift that has been long speculated about in Russia.

Putin's critics have suggested that he is considering various scenarios to retain control of the country after his presidential term ends in 2024, including the option of becoming prime minister with extended powers. Similarly, in 2008 Putin swapped places with the prime minister to circumvent the constitutional provision banning the same person from serving two consecutive terms.
