David Koller

In early 2014, Koller signed an appeal to the Sobotka government, which called for a tougher line towards Russia and the punishment of all Russian minorities in the Czech Republic who have Russian citizenship, namely "immediate suspension of visas for Russian citizens, abolishing the possibility of dual citizenship for Russian citizens, freezing of accounts of Russian citizens in the Czech Republic in order to verify the legality of these deposits, stopping the entry of Russian business and capital into the Czech Republic".
