Ukrainian President Volodymyr Zelensky has said his chief of staff, Andriy Yermak, has resigned following an anti-corruption raid on his home.
Yermak, 54, has been Zelensky's closest adviser throughout Russia's full-scale war, but has come under increasing pressure over an escalating scandal - even though he has not been accused of any wrongdoing.
Zelensky recently appointed his chief of staff to lead crucial negotiations, with US President Donald Trump leading a new drive to end the war with Russia.
In a stark address to the nation, Zelensky called for unity, warning: "We risk losing everything: ourselves, Ukraine, our future."
Ukraine's anti-corruption agencies raided Yermak's apartment in Kyiv's government quarters early on Friday and the chief of staff said on social media that "from my side there is full co-operation".
