Nationalist MP and former Opposition leader Adrian Delia is no longer under investigation for money laundering, the police have confirmed in writing.

In a letter dated October 19, a senior officer from the Financial Crimes Investigations Department informed Delia that the inquiry into his financial affairs had been concluded, Delia said in a message on his Facebook page.

"Unless further evidence or information becomes available, no further police action is anticipated. Accordingly, you are not regarded as a suspect in this matter," the superintendent wrote.

Delia had first sought clarification in September 2022, writing to Police Commissioner Angelo Gafà to request confirmation about the status of the investigation, which he said had caused "irreparable damage" to his reputation and career.

The development brings closure to an inquiry that dates back several years. In January 2020, Times of Malta reported that the probe into Delia's finances had largely stalled, though police had maintained that "investigations are still ongoing."

The allegations were first publicised in 2017 by journalist Daphne Caruana Galizia, who reported that Delia had received money in a Jersey offshore account linked to a London property. The Financial Intelligence Analysis Unit (FIAU) later handed the police a report in 2018 suggesting the accounts "may have been used for money laundering."

Despite the claims dominating much of Delia's tenure as PN leader, the police investigation failed to progress, reportedly hampered by difficulties in obtaining information from foreign jurisdictions and the age of the transactions involved.

Delia was never charged or even questioned by the police during the inquiry.

Announcing the news on Saturday, Delia said the police had now formally confirmed the case was closed.

"Now it is clear these allegations were baseless and false," he said. "The truth is finally out. I broke no law, committed no illegality and was not involved in any money laundering."

He added that he hoped those who had used the allegations against him would acknowledge the harm done.

"We cannot dirty people's reputations, destroy families, and then years later get some form of justice," Delia said.

Delia, a lawyer by profession, continues to serve as a PN MP and spokesperson for finance. Last month he narrowly lost his bid to reclaim the party leadership to Alex Borg.
