In his interview to the Guardian, Berezovsky has claimed to bankroll a coup against Putin.
I don't really understand, what did he try to achieve with this interview, since it only helps to the Kremlin gang to portray him as an ultimate criminal besides Mikhail Hodorkovsky. Actually Kremlin didn't really needed his help anyway since they were doing just fine even beforehand.
Like blaming the assassination of Alexander Litvinenko on him. One of the theories is that Litvinenko was assassinated in order to undermine Berezovsky's refugee status in the UK.
