Which acting Russian President was formally chosen for the post on March 25, 2000?

Vladimir V. Putin was the acting Russian president who was chosen as president in the 2000 election.

Putin became acting president on December 31, 1999, after Boris Yeltsin unexpectedly resigned. Before that, Putin had served as prime minister and had risen rapidly through Russia’s political system after years in the security services. His temporary presidency gave him control of the Kremlin while Russia prepared for an early presidential election.

The election was held on March 26, 2000, and Putin won in the first round with about 53.4 percent of the vote. He defeated Communist candidate Gennady Zyuganov, avoiding a runoff. Putin was formally inaugurated on May 7, 2000. Some historical references place the election-related events on March 25 because of time-zone reporting or differing contemporary accounts, but the identity asked for is unambiguous: Vladimir Putin. The “V.” in the stored answer refers to his patronymic, Vladimirovich.
