Prosecutor-General Ruslan Ryaboshapka has appointed Vitaliy Kasko his first deputy, the press service of the Prosecutor-General's Office (PGO) has said.
From 1999 to 2002, he held positions from a senior investigator to the head of the investigation department in the prosecutor's office of Lviv Region. From 2002 to 2005 he was a senior prosecutor at the PGO.
In 2005-2007, he had legal practice.
He returned to the PGO in 2007 as head of the international law department, where he worked until 2010.
From 2010 to 2014, he worked as a lawyer again.
In 2014, he was appointed deputy to Prosecutor-General Viktor Shokin. Kasko and another Deputy Prosecutor-General David Sakvarelidze, nicknamed "young prosecutors", were considered PGO reformers and had Western support in this regard. At the same time, the USA and the EU have repeatedly demanded the resignation of Prosecutor-General Viktor Shokin and in the end, they achieved it with the help of US Vice President Joe Biden.
After resigning in 2016, he took up advocacy, including defending the interests of the controversial Trade Commodity company, after which he was asked to resign from the board of Transparency International Ukraine.
