KIEV (Reuters) - President Petro Poroshenko is using the breathing space from a ceasefire with separatists to push reforms and rein in super-rich 'oligarchs' whose influence he says must be curbed for Ukraine to have a future in Europe.

But the truce in eastern Ukraine agreed on Feb. 12 is tenuous, with each side accusing the other of violations and the death toll still rising in a year-long conflict that has killed more than 6,100, and most people do not see it lasting.
