Russia was aware of Ukraine's preparations for a counteroffensive even before it began. President Volodymyr Zelenskyy said this at a press conference.
He said that Ukraine now has a military plan, but will not discuss it. The president believes that the fewer people know the army's plan, the faster the victory and the more unexpected the result for the Russians.
"Our counteroffensive actions last autumn were on the Kremlin's table before they began," he said.
He did not say who was behind the leak.
Zelenskyy also added that the format for ending the war would depend on this year.
