Deputy prime minister for anticorruption strategy Karolína Peake announced Tuesday she is leaving Public Affairs (VV), the smallest of the three parties in the center-right coalition, to start a new political platform in a move that observers say could see the embattled party split into factions centered around her and VV de facto chairman Vít Bárta. At least four and as many as ten VV deputies have pledged to join her, media reports say.
