Middleman Melvin Theuma is expected to start testifying in court as from Friday, police sources told The Malta Independent.

Theuma was given a presidential pardon on Monday on the recommendation of Prime Minister Joseph Muscat on condition that his evidence on the Daphne Caruana Galizia murder is corroborated in court.

Theuma will be testifying before Magistrate Neville Camilleri who is leading the inquiry into the assassination.

Theuma was arrested two weeks ago in connection with a money laundering case, the Prime Minister said in a statement last week. He requested a presidentail pardon to give details on the assassination, and this was granted on Monday.

A government statement read that the aim of this is for Theuma to be able to testify about what he knows about the journalist's murder on 16 October, 2017, and other crimes Theuma might have been involved in.

The pardon, the statement read, is subject to a number of conditions that require complete cooperation from Theuma for the truth to come out. The pardon can be withdrawn if Theuma does not observe the conditions, in which case steps could be taken against Theuma even on the basis of the information he himself gives.
