Ukrainian President Viktor Yushchenko on Tuesday, Feb, 10th,2009 called his political rival Prime Minister Yulia Tymoshenko a `traitor` for signing a disadvantageous gas import deal with Russia and secretly agreeing to emergency credits from the Kremlin.`This is nothing less than a betrayal of the national interest,` Yushchenko said at a televised National Security Council meeting. Yushchenko accused Tymoshenko of failing to negotiate a sufficiently low price for gas sold to Ukraine, in exchange for a back channel commitment by the Kremlin to give Kiev 5 billion dollars in emergency credits, among other alleged errors.
