Czech President Milos Zeman was released from Prague’s Central Military Hospital on Friday after a one-day stay, according to news agency CTK.

Zeman, 77, has been using a wheelchair and was hospitalized for more than six weeks last year with an unnamed medical disease that temporarily questioned his capacity to complete his duties.

Zeman is the head of state and has powers including the appointment of prime ministers and central bank leaders, but most executive power is in the hands of the government.

Zeman’s final five-year term ends in March next year.

The president’s spokesman did not immediately respond to Reuters’ request for comment.
