MOSCOW. Oct 24 (Interfax) - State Duma Deputy and journalist Alexander Khinshtein has brought out a book exposing alleged murky dealings by Russian tycoons Boris Berezovsky and Roman Abramovich and had it launched on Wednesday.

A summary of the book, entitled "Berezovsky & Abramovich. Brigand Oligarchs," describes it as one of a series of books on "corruption scandals and exposures" and says that "this time it is the powers that be that come into the focus of the author's attention."

The book is supplemented with two compact disks - "sensational records of telephone conversations" allegedly done by private security firm Atoll, which Berezovsky used to own.

The voices on the disks are said to be those of many high-profile figures.

In addition to Berezovsky and Abramovich, the alleged speakers include Tatyana Dyachenko, daughter of former Russian president Boris Yeltsin; Anatoly Chubais, a politician and today chief executive of Russian national electricity company UES; Viktor Chernomyrdin, a former Russian prime minister and today Russian ambassador to Ukraine; Valentin Yumashev, Yeltsin's one-time chief of staff; Alexander Lebed, a former secretary of the Russian Security Council; Andrei Lugovoi, the suspected murderer of Alexander Litvinenko; Litvinenko himself; and Leonid Nevzlin, a former co-owner of Russian oil company Yukos.

Khinshtein did not disclose how the recordings had ended up in his hands.

Asked whether he expected any of those whose voices are allegedly recorded on the disks to sue him, he said: "I will be glad if they do. The edition will double in size."

The 600-page book has come out in an edition of 50,000.
