Former government ministers Chris Fearne and Edward Scicluna will be criminally charged in court on 29 May.
Fearne resigned from minister last week following the conclusion of the mahgisterial inquiry into the deal seeing three public hospitals being passed on to the provate sector.
Scicluna, who is now Central Bank of Malta, has not resigned in spite of calls for him to quit his job.
Fearne and Scicluna are among a list of 15 people set to be charged with fraud.
They will be charged a day after former Prime Minister Joseph Muscat, former Minister Konrad Mizzi and former OPM chief of staff Keith Schembri will face different charges related to the same inquiry.
The individuals charged alongside Fearne and Scicluna include former permanent secretaries Alfred Camilleri and Joseph Rapa, current permanent secretary Ronald Mizzi, adjudication committee members James Camenzuli, Manuel Castagna, and Robert Borg, financial controller Kenneth Deguara, and five lawyers: Kevin Deguara, Jean Carl Farrugia, Aron Mifsud Bonnici, Deborah Anne Chappell, and Bradley Gatt.
