KIEV, 06 Ramadan, 1435, 03 July, 2014, SPA - - Ukrainian President Petro Poroshenko has nominated a new defence minister and appointed a new armed forces chief in a shake up of a military currently driving against Russian separatists despite moves for a new ceasefire, Reuters reported. Poroshenko told deputies on Wednesday night that he wanted Valery Heletey, a 46-year-old colonel-general who heads security at the presidential and parliamentary administration, to replace acting defence minister Mykhailo Koval, his website said. He also appointed lieutenant-general Viktor Muzhenko, 52, a top official in the military drive against the rebels, to replace Mykhailo Kutsyn as head of the general staff. Poroshenko was expected to seek endorsement for Heletey's nomination at a session of parliament on Thursday. --SPA 12:55 LOCAL TIME 09:55 GMT www.spa.gov.sa/w
