Czech communists have been members of parliament consistently since revolution so it's not very surprising they might become part of the government at some point. Most left-wing and right-wing Czech politicians including all Czech presidents have been members of communist party at some point in their life. So in reality, Czech republic had communists in power ever since the revolution. Czech communist party is standard left-wing party. They just didn't drop the name "communist" like everybody else did. That's all.
