A total of 383 State Duma lawmakers voted in favour of the package of constitutional amendments, with 43 abstentions and none against.

The measures must now be approved by the upper house Federation Council and be put to a public vote scheduled for April 22.

Putin announced the package of reforms in January.

On Tuesday another amendment was introduced that would reset presidential terms, making it possible for Putin to run again if the constitutional court allows it.

Other additions to the constitution include guarantees for pension payouts and minimum salaries, and giving parliament additional power to nominate the head of government. 

They also give the president additional powers to fire judges in the country's higher courts and to reject laws passed by parliament.
