Ukrainian President Viktor Yanukovych has assured UK Prime Minister David Cameron that Ukraine will remain a democratic state, despite the recent reversal of a 2004 reform that curbed presidential powers, according to RIA Novosti.

Ukraine`s Constitutional Court boosted Yanukovych`s powers by ruling that the 2004 reform, introduced during the Orange Revolution that brought ex-president Viktor Yushchenko to power, had been unconstitutional.

"The decision by the Constitutional Court has taken Ukraine back to a legal framework," he told Cameron during a recent telephone conversation.

"I, more than anyone else, want processes in Ukraine to be both transparent and democratic," he said.

The opposition says the move means that Ukraine, like neighboring Belarus, is becoming increasingly authoritarian.
