Ukrainian President Petro Poroshenko handed to the US Embassy in Kiev inside information on the forging of a coalition government in 2006, according to Wikileaks data.



Russia's RIA Novosti agency, citing the purported evidence, tried to inform Ambassador John Herbst in April 2006 on the situation, describing himself as an insider from the party Nasha Ukrayina (Our Ukraine), a bloc associated with former President Viktor Yushchenko.



Cables sent from the Embassy to the US State Department however suggest that the diplomat doubted the authenticity of Poroshenko's information and considered it to be part of backdoor games aimed at arresting Yuliya Tymoshenko (former Prime Minister) and Oleksandr Turchynov (acting President before Poroshenko's election).



The two were once allies to Yushchenko, but discrepancies led to mutual accusations just years on from the 2004 Orange Revolution. Poroshenko, on the other hand, took part in the coalition discussions as lawmaker and close to President Yushchenko.



A billionaire confectionary magnate, Poroshenko is seen as a controversial figure, with some relying on him to wind down tensions in east Ukraine and others reminding he is an "oligarch" who has always maintained his strings in politics regardless of who was in power.
