Bulgaria's former Prime Minister and leader of opposition centre-right GERB party, Boyko Borissov, has been detained late on Thursday as part of a police operation linked with the probes of the EU prosecutor's office, the interior ministry said.
Former Finance Minister Vladislav Goranov, the former chair of the parliamentary budgetary commission Menda Stoyanova as well as Borissov's media adviser Sevdalina Arnaudova were also detained, the ministry said in a statement.
