Sergei V. Kiriyenko, once one of the young reformers of post-Soviet politics, now holds the centre of President Vladimir V. Putin's wartime machine. As deputy chief of staff first, he is the Kremlin's go-to guy for directing its most politically sensitive operations — from holding referendums in Russian-occupied parts of Ukraine to taking control of Russia's internet and cultural space.

Kiriyenko's influence goes beyond internal politics, seized Ukrainian territory, and Russia's broader geopolitical periphery. He has since 2022 overseen pseudo "elections" in annexed Ukrainian territories, advocated pro-Kremlin ideology in education, and called on officials to take up administrative roles in occupied regions. Beyond Ukraine, he is tasked with coordinating Kremlin efforts in breakaway republics such as Abkhazia, Georgia, and within Moldova — duties previously wielded by senior aides out of favour.
