US and European officials have been discussing how the West would support a government in exile helmed by Ukrainian President Volodymyr Zelensky should he have to flee Kyiv, Western officials told CNN.

The discussions have ranged from supporting Zelensky and top Ukrainian officials in a potential move to Lviv in western Ukraine, to the possibility that Zelensky and his aides are forced to flee Ukraine altogether and establish a new government in Poland, the officials said.

The discussions are only preliminary and no decisions have been made, the sources said.

Western officials have also been wary of discussing a government in exile directly with Zelensky because he wants to stay in Kyiv and has so far rejected conversations that focus on anything other than boosting Ukraine in its fight against Russia, two Western diplomats said. They added that there have been discussions about sending one or more members of Zelensky’s government to an external location where a government could be set up in case Kyiv falls and Zelensky is unwilling or unable to get out.
