Ukraine president says compromise with Russia will require a referendum

Ukrainian President Volodymyr Zelenskiy on Monday said any compromises agreed with Russia to end the war would need to be voted on by Ukrainians in a referendum.

"The people will have to speak up and respond to this or that form of compromise. And what they (the compromises) will be is the subject of our talks and understanding between Ukraine and Russia," he said in an interview published by Ukrainian public broadcasting company Suspilne.

Issues that could be raised in any referendum could concern territories occupied by Russian forces, including Crimea, or security guarantees offered to Ukraine by countries in lieu of NATO membership, he said.

Zelenskiy also said that Ukraine would never bow to ultimatums from Russia and cities such as Kyiv, Mariupol or Kharkiv would not accept Russian occupation.

"We have an ultimatum with points in it. 'Follow it and then we will end the war'," Zelenskiy said in an interview published by Ukrainian public broadcasting company Suspilne. "Ukraine cannot fulfil the ultimatum."
