Mikhail Mishustin was confirmed as Russia's next prime minister on Thursday.

Mishustin was nominated by Putin for the position after the previous prime minister Dimitri Medvedev resigned on Wednesday.

Medvedev's resignation came amid a proposal for sweeping constitutional reform in Russia from Putin.

Mishustin was formerly the head of the Federal Tax Service, and appears to be fairly unknown publicly in Russia.

Former tax official Mikhail Mishustin was announced as Russia's next prime minister on Wednesday.

The announcement was made amid a proposal for sweeping constitutional changes from Russia's president Vladimir Putin — a move thought to be a push from Putin to increase his own political power.

Mishustin received 383 votes out of 424 in Russia's parliament, with 41 abstentions and no votes against him, according to Reuters.

53-year-old Mishustin has a reputation for being an efficient technocrat, but is not very well known among the public in Russia, according to Foreign Policy.
