Off the top of my head, I can’t think of another time in the last 10 years that a government has fallen while it held the EU presidency. Given the present rotation, the Czechs won’t get another chance until the 2020s. Oops.
Topolanek will stay on as a caretaker until Czech President Vaclav Klaus names a new prime minister who can assemble a working coalition in parliament. If three attempts to form a government fail, early elections must be called. What a mess!
