A Ukrainian court has ordered the country’s richest tycoon Ihor Kolomoisk to be held in custody for two months on suspicion of fraud and money laundering. The detention of the one-time supporter of president Volodymyr Zelensky, whose election he backed in 2019, comes as Kyiv is trying to signal progress during a wartime crackdown on corruption. Following the arrest, Mr Zelensky made an oblique reference to the case and thanked law enforcement bodies for their work on long-running cases. “I thank Ukrainian law enforcement officials for their resolve in bringing to a just outcome each and every one of the cases that have been hindered for decades,” Mr Zelensky said in his nightly video address. Meanwhile, Ukraine has claimed to have broken through the first line of Russia’s defences in several locations in the south and made gains in the Zaporizhzhia region. “There is an offensive in several directions and in certain areas. And in some places, in certain areas, this first line was broken through,” Hanna Maliar, deputy defence minister, told local TV on Friday night.
