Babis, 63, a member of the Communist party before 1989, said he would defend himself against the charges of collusion with the StB which are based on state historical archives.
“I understand that people don’t like me. They are influenced by the hundred-times repeated lies. I will sue Slovakia by June 15 at the European Court for Human Rights,” he told reporters on Wednesday.
Babis has admitted to meetings with StB officers in the 1980s in the former Czechoslovakia when he was a Communist Party member and worked in foreign trade, but he insists he only discussed the country’s economic interests.
The prospect of Communists getting a share of power again sparked another wave of protests on Tuesday, bringing thousands of people to the streets.
