The European Federation of Journalists has reported Daphne Caruana Galizia's case to the Council of Europe Platform for the Protection of Journalism.
The EFJ is the European regional organisation of the International Federation of Journalists. It is the largest organisation of journalists in Europe, representing about 320,000 journalists in 71 journalists' organisations across 43 countries
This comes after Minister Chris Cardona and his EU presidency policy officer Joseph Gerada filed four precautionary warrants which froze €47,460 of Mrs Caruana Galizia's bank account.
The Labour Party deputy leader and Mr Gerada filed for libel after Mrs Caruana Galizia published articles onto her website which alleged that both men had visited a brothel while on official business in Germany.
Mrs Caruana Galizia claims that a source, who is a Maltese national, witnessed the two men inside the brothel.
