Matthew Caruana Galizia told jurors that his mother had been receiving emails and documents from a source inside Electrogas as part of her investigations into the power station project.Testifying in the trial by jury of Yorgen Fenech, Caruana Galizia said Daphne had shown him some of the material and told him there were thousands of other documents still to come.He said they both understood the risk involved, because the person sending the information could have exposed themselves in the process.“I was travelling to Malta more often and couldn’t believe what she was doing. She used to blow my mind,” he told the court.Caruana Galizia also referred to Nexia BT, the financial services firm linked to the Panama Papers structures of former OPM chief of staff Keith Schembri and former minister Konrad Mizzi.“It was a portal opening up and I could see hell,” he said.The defence immediately objected, arguing that the witness was giving an opinion rather than limiting himself to facts.The exchange briefly escalated when lawyer Jason Azzopardi was fined €50 by the court after shouting “Shame!” at defence lawyer Charles Mercieca, who had objected to the witness.The defence later objected again, saying prosecutors had referred Caruana Galizia to an email that was not in evidence and which the witness had neither written nor received.Caruana Galizia said Electrogas appeared to be “linked to everything”.He told the court the documents suggested the company was under pressure, and that once he began organising the material, Yorgen Fenech’s name kept appearing.“I could see that Yorgen Fenech seemed to be at the centre of everything,” he said.He said he and his mother had planned to carry out a major Electrogas investigation by processing the documents they had gathered, together with the information received from the source.That work was never completed.“When I see those emails, my heart starts beating faster,” he said. “I’m taken back to what we were supposed to do.”Caruana Galizia also recalled travelling to the United Arab Emirates after his mother’s murder with Reuters journalist Stephen Grey, as he tried to identify who was behind offshore companies linked to the case.“The last time I was in the UAE was the day before the arrest of Yorgen Fenech,” he said.He told the court that he went to a Dubai company register and made up an excuse to go to the bathroom, where he found computers and began searching for information.A lawyer later approached him and asked if he needed help. Caruana Galizia said he told her his mother had been murdered.According to his testimony, the lawyer went to check something and appeared sympathetic, but his request for information was ultimately rejected.“The next morning, a journalist told me Yorgen Fenech had been arrested,” he said.Electrogas was one of Malta’s largest infrastructure projects in recent years, involving a new power station and LNG terminal at Delimara. Fenech was a shareholder in the consortium through GEM Holdings.Fenech is accused of complicity in Caruana Galizia’s murder and involvement in a criminal organisation. He denies the charges.•
