(1989), ka hoki mai ia ki Czechoslovakia ka whakahoutia te roopu, ka noho hei kaiarahi. I te wa o te pooti 1990, kaore i taea e te roopu te whiwhi nohoanga i te whare paremata; I uru hoki a Horák ki nga tautohetohe a-roto. I ngā pōtitanga o te tau 1992, ka whiwhi te rōpū i te aroaro ā-paremata. I te tau 1993, ko Miloš Zeman te whakakapi i a Horák hei kaiarahi o te roopu.
