Estonia’s Prime Minister, Kaja Kallas, suggested that local businessman Parvel Pruunsild, majority owner of Bigbank, made major donations to opposition parties in order to break up the first coalition government that Kallas headed, ERR reports. In response, Pruunsild’s lawyer sent a letter to Kallas, demanding that she retract her statement and issue an apology. Kallas refused to do so, saying thay she did not consider the rumours regarding the objectives of Pruunsild’s donations to be unfounded. She urged Pruunsild to convince everyone that his donations did not come with strings attached. Earlier, the governing board of the opposition Estonian Centre Party (Keskerakond) voted to return Pruunsild’s donation, prompting an internal party rift.
