In recent days Ukrainian MPs failed to form new governing coalition
Ukraine's President Petro Poroshenko is leaving for Washington to take part in a nuclear security summit.
He had been hoping to present the US government with a list of members of Ukraine's new coalition in order to unlock a USD 1.7 billion loan from the IMF. But talks in Kyiv are ongoing.
Former Ukrainian Prime Minister Yulia Tymoshenko's 'Bat'kivschyna' (Fatherland party) has put forward new set of demands, which includes lowering the cost of utilities and scrapping a tax on pensions.
Members of Poroshenko's bloc say this goes against the IMF's requirements for a bailout.
