Dmitry Kozak, only senior Russian official thought to oppose the war, resigns as Kremlin deputy chief of staff
Update: The Kremlin confirmed on Thursday that Dmitry Kozak has left his post as Putin’s deputy chief of staff. “I can confirm that Mr. Kozak has resigned. Of his own accord,” Kremlin spokesperson Dmitry Peskov said at a press briefing.
Vladimir Putin’s Deputy Chief of Staff Dmitry Kozak has submitted his resignation, RBC reported, citing two sources.
According to the outlet, Kozak is weighing “various offers to move into business.”
Journalist Alexey Venediktov and political analyst Arkady Dubnov also reported his departure, citing their own sources.
Kozak is one of President Vladimir Putin’s oldest associates. The two worked together in the St. Petersburg mayor’s office in the 1990s. Since the early 2000s, Kozak has held a series of senior posts in both the cabinet and the Kremlin. From 2008 to 2020, he served as deputy prime minister, and in 2020 he became deputy chief of staff of the presidential administration.
In early August, The New York Times, citing sources, reported that back in 2022, Kozak advised Putin not to invade Ukraine. In 2025, he reportedly urged the president to begin peace talks and pursue domestic reforms, including placing Russia’s security services under government control.
