Here's an interesting piece from Prof Andrei Zagorski, a political analyst at Moscow's Institute of World Economy and International Relations.
Extract.....
"Ukraine has restored its 2004 constitution, which empowers parliament and the government, rather than the president. So a resolution of the political legitimacy crisis in Ukraine will depend not so much on the expected presidential elections in May, but on the anticipated parliamentary elections in summer.
The parliamentary elections may provide Russia and EU with more incentives to co-operate. Neither Moscow nor Brussels are interested in a collapsing Ukraine. Both should be interested in the establishment of a legitimate government and, for that reason, in fair elections. Brussels will want to see a government that enjoys maximum popular support, and Moscow will want a rebalancing of the current political constellation in Kiev.
It would be best - for the EU and Russia - to postpone any decision to sign the EU-Ukraine association agreement.
It was Mr Yanukovych's refusal to sign that deal which triggered the protests back in November. But if Ukraine were to sign it now it would be interpreted in Moscow as a strategic defeat. The deal could be signed once the political and financial situation in Ukraine has stabilised.
