Taking a cue from President Dmitry Medvedev's transparency drive, a senior Interior Ministry official said Wednesday that rank-and-file police officers -- widely seen as the country's most corrupt public servants -- will be required to show their tax declarations to their bosses.

Beginning next year, all police officers will be required to present their tax declarations to their superiors, including information about the income and assets of their spouses and underage children, said Vladimir Kikot, head of the ministry's personnel department.

It was not immediately clear whether the declarations would be made public like those of senior government officials, who, under a decree signed by Medvedev this month, are required to publish their earnings.

The police officers' declarations "may be presented to the media as envisaged by law," Kikot said cryptically without elaborating, Interfax reported.

Repeated calls to the Interior Ministry's personnel department and the ministry's press office went unanswered.

Officers who fail to present tax declarations or who provide false or incomplete information may be fired or subject to other punishments, Kikot said.

Public opinion polls consistently show the police as one of the country's least trusted institutions, and senior law enforcement and government officials concede that corruption is rampant.

As part of his anti-corruption campaign, Medvedev has signed a number of decrees this year ordering certain senior officials to publish information about their incomes and property. One decree requires the tax declarations to be published on government web sites or released to journalists within one week of an official request. The president, prime minister and Cabinet members are now required to submit their declarations by April 1, while other officials should follow suit by April 30.

This year, many senior officials, including Medvedev, released their tax declarations, although they are required by law to do so only starting next year.
