New Ukraine chief of staff revealed by Zelensky at key moment in Russia war

Ukraine President Volodymyr Zelensky has appointed General Kyrylo Budanov, the country’s military intelligence chief, as his new chief of staff.

This significant change comes at a particularly critical juncture in Russia’s nearly four-year invasion.

General Budanov replaces Andrii Yermak, President Zelensky’s long-standing aide, who resigned in November.

Yermak’s departure followed an anti-corruption raid on his apartment, investigating alleged graft in Ukraine’s energy sector.

The removal of such a powerful figure was considered a blow to the president, potentially jeopardising his negotiating strategy amidst US peace efforts.

Here’s what you need to know about Budanov:

Rising through the ranks

Budanov has led the military intelligence agency, known by its acronym GUR, since 2020. At 39, he is one of Ukraine’s most recognizable and popular wartime figures, known for being the architect of many successful operations targeting Russian military assets, as well as for his independent and enigmatic personality.

A career military intelligence officer, Budanov brings battlefield knowledge to his new position.

He rose through the defense establishment after Russia’s illegal annexation of Crimea in 2014. He also took part in special operations and intelligence missions linked to the fighting with Moscow-backed separatist forces in eastern Ukraine and Crimea before the full-scale invasion of February 2022. He reportedly was wounded during one such operation.

Taking the war to Russian-held territory

Since that invasion, Budanov has become a prominent face of Kyiv’s intelligence effort, appearing regularly in interviews and briefings that mix strategic signaling with psychological pressure on Russia. He has warned frequently of Moscow’s long-term intentions toward Ukraine and the region, portraying the war as an existential struggle for the country’s statehood.

Under Budanov, the GUR expanded its footprint, coordinating intelligence, sabotage and special operations aimed at degrading Russia’s military capabilities far beyond the front lines.

Officials have credited the military intelligence service with operations targeting Russian command structures, logistics hubs, energy infrastructure and naval assets, including attacks deep inside Russian territory and occupied areas of Ukraine.

Targeted by Russia

Budanov’s role and public status has made him a target. He reportedly has survived multiple assassination attempts by the Russian security services. In November 2023, his wife, Marianna, was hospitalized in Kyiv with heavy metals poisoning.

His appointment to lead the presidential administration signals a shift at the heart of government to prioritize foreign policy, defense and security amid the intensifying diplomatic efforts to end Russia’s invasion. Zelensky says a peace deal is “90 per cent ready” but warned that the remaining 10 per cent — believed to include key issues such as territory — would “determine the fate of peace, the fate of Ukraine and Europe.”

Budanov served as part of the delegation that worked with the U.S. negotiating team. He also has had contact with the Russian side on issues such as coordinating prisoner exchanges. It’s not yet clear what role, if any, he will take in the peace process in his new position.

In his first comments after the appointment was announced, Budanov thanked Zelensky for his trust.

“I continue to serve Ukraine,” he wrote on his Telegram page. “For me, it is both an honor and a responsibility — at a historic time for Ukraine — to focus on the critically important issues of the state’s strategic security.”
