Fiala, like everyone else at the ceremony, was wearing a respirator when he signed the official document in front of Zaman, who was seated in a box specially built for the ceremony.
As soon as the results were announced, the two coalitions signed a memorandum of understanding to form a government to oust the current populist Prime Minister Andrzej Babis.
One day after the election, 77-year-old Zaman was taken to hospital, where he spent several weeks in intensive care for liver and other serious health problems.
Choosing the next prime minister to form a government is one of the president’s key constitutional roles, so being admitted to a German hospital has put the country in a political stalemate.
Jeeman was released from the hospital 46 days later on Thursday morning and was sent back in the evening after a positive test for Kovit-19.
Kovid was released again on Saturday on condition that he remain in solitary confinement, with no signs of recovery.
During the ceremony, Zeman and Fiala spoke to each other using a microphone. Zaman said he would next meet separately with Fila’s future cabinet members and said he wanted to complete the process by December 13.
Until then, the new government will be formed and will receive a vote of confidence in the lower house of the Czech parliament, with Babis and his government in power.
