KIEV, April 5 - Ukraine's fiscal service will examine the documents relating to President Petro Poroshenko's offshore assets that were published over the weekend after a massive data leak, the head of the service, Roman Nasirov, said on Tuesday.

"We will analyze the information that was presented in the press, that which we can analyze, and we will let you know," Reuters quoted Nasirov as saying when asked by reporters about the data leak.

Poroshenko said Monday that he is committed to transparency after lawmakers called for an investigation into allegations contained in Panama Papers that he had used an offshore firm to avoid tax.

Ukraine’s general prosecutor's office has seen no evidence that Poroshenko committed a crime based on leaked documents regarding alleged offshore assets, a senior official for the office said on Monday.

The leak over the weekend gave details of hundreds of thousands of clients in more than 11.5 million documents from the files of law firm Mossack Fonseca, based in the tax haven of Panama.

According to the International Consortium of Investigative Journalists, Poroshenko set up an offshore company to move his confectionery business, Roshen, to the British Virgin Islands in August 2014 during a peak in fighting between Ukraine and pro-Russian separatists.

In response, Poroshenko said he had handed over the management of his assets to consulting and law firms on taking office.

The law firm tasked with managing the sale of Roshen said the offshore firm was set up in accordance with Ukrainian law.

Poroshenko's financial adviser, Makar Paseniuk, said the offshore firm was created to avoid a conflict of interests by allowing his assets to be controlled by third parties while he remained president.

The IMF, the United States and the European Union are becoming frustrated with Ukraine's patchy performance in tackling graft, and the Fund has threatened to halt aid until matters improve.

Poroshenko, who came to power after protests in 2014, has already faced criticism for not selling Roshen despite promising to do so.

Paseniuk said there had been no credible offers for the company so far, prompting those managing the sale to consider selling it off in parts. Talks to sell Roshen's Russia-based Lipetsk factory were continuing, he said. (rt/ez)
