Heraldo de Madrid - Ukraine targets oligarch, ex-minister in graft clampdown

The searches came ahead of a key summit with the EU and appeared to be part of a push by Kyiv to reassure key military and financial donors in European capitals and Washington that Ukraine is tackling systemic graft.

"We are carrying out the task set by Ukrainian President Volodymyr Zelensky and simultaneously delivering a global blow to the internal enemy," announced Vasyl Maliuk, the head of Ukraine's security service, the SBU.

"Every criminal who has the audacity to harm Ukraine, especially in the conditions of war, must clearly understand that we will put handcuffs on him."

The searches have targeted influential billionaire Igor Kolomoisky and former interior minister Arsen Avakov, said the head of Zelensky's party David Arakhamia.

Law enforcement also raided tax offices in the capital and senior customs officials were fired, Arakhamia said.

Ukraine for years has suffered endemic graft but efforts to stamp out corruption have been overshadowed by Moscow's invasion last February.

Ukraine has now launched a new push to clean up its image to appease Western backers.

In the biggest political shakeup since the launch of Moscow's assault on Ukraine, authorities last week fired around a dozen senior figures, including defence officials and a top aide to the president's office.

The raids on Wednesday came two days before Zelensky was expected to host a summit with the European Union, which has urged reforms to facilitate deeper integration.

Investigators from the SBU released images of a search from the home of Kolomoisky who was barred from entering the United States over allegations of corruption and undermining democracy.

- 'All necessary steps' -

Prior to the invasion, Kolomoisky was one of the country's richest men with holdings in a slew of industries, including media, aviation and energy.

The security service said the search had been launched in connection with an investigation into the embezzlement of 40 billion hryvnia (more than a billion dollars) from energy holdings.

The Ukrainian government seized stakes in the energy companies -- oil producer Ukrnafta and refiner Ukrtatnafta -- as part of moves to consolidate the war effort.

The SBU also said it had uncovered a scheme by the head of the Kyiv tax office over "multimillion-dollar" fraud schemes, accusing the official of abusing a position of authority.

In an address to the nation on Tuesday, Zelensky vowed officials would take further measures to sweep away graft, saying "all the necessary steps have already been taken."

"People in the government who do not meet the basic requirements of the state and society should not occupy their seats," he said.

The State Bureau of Investigation and the Prosecutor General's Office said on Wednesday that they had informed a number of senior officials they were being investigated for crimes including misappropriation of state funds and misuse of state property.

Last week the defence ministry announced the resignation of deputy minister Vyacheslav Shapovalov, who was involved in logistical support for the army.

That resignation came after the ministry was accused of signing food contracts at prices two to three times higher that market rates for basics.

- Donetsk battle getting 'worse' -

Despite being vocal about fighting corruption, Zelensky himself has been embroiled in corruption scandals in the past, and previously he was seen as harbouring links with Kolomoisky.

He is now working to drum up political backing for Ukraine at a critical time in the conflict, with Russian forces claiming to have captured fresh ground in the eastern Donetsk region.

AFP journalists near the small town of Vugledar in the battle-scarred industrial region this week witnessed artillery barrages to keep Russian forces at bay.

"The more time passes, the worse the situation gets," Oleksandr, 45, said from a trench just five kilometres (three miles) from Vugledar.

Ukrainian Foreign Minister Dmytro Kuleba said Tuesday that a dozen countries had promised more than 100 tanks after Germany and the United States signed off on the deliveries last week.

Now Zelensky and other Ukrainian officials are calling on the West to supply fighter jets and long-range artillery too.

"It would require greater efforts from us. But again, it won't change the course of events," Kremlin spokesman Dmitry Peskov told journalists.
