Wistrill said long-term predictions about the president’s health were very uncertain.
Zemans was hospitalized on October 10.
Wistrill said Zemans was unlikely to be able to work in the coming weeks, according to information he received from the hospital.
Zemann may be subject to impeachment proceedings or may be temporarily relieved of his duties by a simple majority in both houses of parliament.
The Senate will discuss the next steps tomorrow.
Zeman has a crucial role to play after the election, as the president decides who to entrust the formation of the government, and he should now choose between the former prime minister and ancient ally Andrei Babiss and the right-wing MP Peter Fial, whose coalition “Together” won the parliamentary elections.
Zeman was hospitalized shortly after a meeting with Babish, who later announced that Zeman had promised to entrust him with the formation of a new government.
Czech media report that the president has serious liver problems, but the information available is scant.
