Kiev – A Ukrainian court on Tuesday sentenced former prime minister Yulia Tymoshenko to seven years in prison for abuse of office in relation to a 2009 gas deal with Russia.

Tymoshenko is said to have brokered the deal.

“The court has found Tymoshenko guilty and sentenced her to a prison term of seven years,” judge Rodion Kireyev said.

Kireyev handed down the sentence, the maximum sought by state prosecutors in a lengthy judgment at the end of a three-month trial which has polarised society in the ex-Soviet republic and risks jeopardising relations with the West.

The European Union, a big trading partner for Ukraine, has warned that jailing the charismatic opposition leader will put at risk ratification of an association agreement due to be signed later this year.

Tymoshenko, 50, smiled as Kireyev pronounced his sentence, and then rose to her feet even as he continued to read his judgment, and in a monotone denounced the “authoritarian regime” of President Viktor Yanukovich and decried the lack of justice in Ukraine under him.

Earlier Kireyev said she had exceeded her powers in rail-roading the state energy firm Naftogaz into signing a 10-year gas supply deal with Russia in 2009 which ended with Ukraine paying an exorbitant price for gas.
