Hungary’s political civil war is beginning to boil over as the head of government prepares to remove the president with a bespoke amendment of the constitution that would strip him of office.

Prime Minister Peter Magyar submitted a proposal for a constitutional amendment over the weekend that would remove President Tamas Sulyok as head of state. The 17th amendment to the Fundamental Law, if passed by the Hungarian Parliament, would end Sulyok’s leadership the day after going into effect and give lawmakers 30 days to select a replacement.
