VALLETTA (Reuters) - The self-confessed middleman in the murder of a journalist told a court on Wednesday a wealthy Maltese businessman was the brains behind the killing but also implicated people tied to government in the growing scandal.

Melvin Theuma received immunity from prosecution last week for information that would lead to the conviction of alleged plot leader and multi-millionaire entrepreneur Yorgen Fenech.

However, his detailed court deposition raised fresh questions over the inner circle of Prime Minister Joseph Muscat, with Theuma linking apparent attempts at a cover-up of the 2017 murder to figures inside government headquarters.

Fenech has been charged with complicity over the killing of anti-corruption journalist Daphne Caruana Galizia by a car bomb. He has denied the accusations and blamed former government chief of staff Keith Schembri and other senior officials.

Schembri was arrested last month but later released. He has denied involvement in the murder which has highlighted allegations of rampant corruption in Malta’s overlapping worlds of politics and business.

Theuma gave a detailed account of how the 38-year-old Fenech contacted him in 2017 to organize the hit, providing 150,000 euros ($165,000) for the contract.

The plot was put on hold before elections in June 2017 but reactivated the night the ruling Labour party was returned to power, Theuma told a packed courtroom.

“I can assure you, Yorgen Fenech was the only mastermind. Only he spoke to me,” said Theuma, a taxi driver with links to the criminal underworld.

Fenech wanted Caruana Galizia dead because he thought she was going to publish an incriminating story about his uncle, Theuma said.

He said he was called to government headquarters after agreeing to arrange the assassination and that Schembri gave him a tour of the building, where Muscat’s offices are housed.

Muscat has denied any wrongdoing but has acknowledged he could have handled the aftermath better and said he will step down next month.

PANIC

Theuma was subsequently told he had been put on the government payroll and received a paycheck for three or four months. “If you asked me, I wouldn’t know what my job was at the ministry, as I never went,” he said.

He said he paid three local men to carry out the killing. Thanks partly to help provided by the U.S. FBI, the trio were later arrested, and are awaiting trial, having pleaded not guilty. They sat in court on Wednesday stony-faced.

Theuma recounted his panic after the alleged triggermen were seized and news emerged that one was cooperating with police.

He said he was then contacted again by an employee from government headquarters whom he named as Kenneth. In an apparent attempt to buy their silence, Kenneth said the three suspects would be released on bail and given 1 million euros, though the bail did not arrive, Theuma said.

Theuma said he asked Fenech whether Schembri had sent Kenneth to him, but got no answer. Scared for his safety, he started making secret recordings of his conversations with the businessman, which he has given police.

“I started to think they would either lock me up or kill me,” he said. He also acknowledged writing a note where he said both Schembri and Fenech ordered the hit. In court, he distanced himself from the accusation against Schembri, making clear he had no evidence.

A police source later identified Kenneth as Kenneth Camilleri, who used to work in Muscat’s security detail. He was recently transferred to Transport Malta, a government body. The company said on Wednesday it had suspended one of its employees following Theuma’s deposition, without giving details.

Camilleri did not respond to a message from Reuters requesting comment.

With Malta under scrutiny, the new head of the EU executive, Ursula von der Leyen, urged a thorough investigation without political interference. “It is crucial that all those responsible are put to justice as soon as possible,” she said.

A European Parliament delegation, which has spent two days in Malta to review rule of law within the EU’s smallest member, recommended that Muscat go immediately.

“There has to be absolute confidence in the (investigation) and I think when he is in office, that confidence is not there,” said Sophie In’t Veld, a Dutch member of parliament who led the mission.
