Last year, a Pandora Papers leak revealed that Mr Zelensky, who campaigned on promises to “break the system” of oligarchic control and corruption in Ukraine, set up a spider web of offshore companies in 2012. Zelensky’s office justified the move by saying they were a form of “protection” against former President Viktor Yanukovych.

A Dutch political party has taken an interest in Ukrainian President Volodymyr Zelensky’s personal finances.

“Zelensky has a fortune: various estimates put his wealth at around $850 million. He amassed most of it after taking office as president. Where does the money come from? And more importantly, where is it going?” the Forum for Democracy asked in posts on its Twitter and Telegram accounts on Monday.

The Dutch national conservative and hardline Eurosceptic party boycotted Zelensky’s speech to the Dutch parliament last month, denouncing it as a violation of nearly two centuries of democratic tradition, which forbid foreign heads of state from speaking before the House of Representatives.

The party also expressed concerns about Zelensky’s ban of political parties, including the main opposition party, and the shuttering of TV channels critical of his regime.
