MOSCOW—After a community of investigative journalists uncovered documents appearing to show that scores of world leaders and public officials could be engaged in money laundering, tax avoidance, and various forms of financial wrongdoing, the disclosures were splashed liberally on front pages around the world.

But in Russia, coverage was spottier.

Reporting by the International Committee of International Journalists (ICIJ) in Russia’s newspapers and online media that close associates of President Vladimir Putin hid money offshore appeared to be divided along political lines, with the clutch of liberal-minded independent outlets giving the findings generous coverage.

Initially Russian television stations, which set the news agenda across the country’s 11 time zones, entirely skipped the so-called Panama Papers, leading instead with revelations of a doping scandal—in London.

State-run Rossia 1 and First Channel, and private stations REN-TV and NTV, failed to mention any aspect of the report in lengthy morning-news programming on April 4. Their segments led with news of a fire in Tomsk, the Syria crisis, and the migrant crisis in the European Union.

The stations meted out special attention to a doping scandal in London exposed by the Sunday Times on April 3 in which a private British doctor said he prescribed performance-enhancing drugs to 150 athletes from Britain and abroad.
