KIEV (Reuters) - Former Ukrainian Prime Minister Yulia Tymoshenko used a pre-trial hearing Friday to allege President Viktor Yanukovich was behind a crooked court action that was certain to convict her of abuse of power. The case involving Tymoshenko, twice prime minister and now in opposition, has raised concerns among Western governments over Yanukovich's commitment to democracy and the rule of law. Hemmed in by TV cameraman and journalists in the tiny Kiev courtroom, the 50-year-old Tymoshenko called on all her oratorical skills as she denounced the hearing as an arranged "farce" and told the judge he was a Yanukovich "puppet."
