Mark Rutte has reportedly asked allies to devote 0.25% of their GDP to supporting Kiev

NATO Secretary General Mark Rutte has urged member states to devote 0.25% of their GDP to aid for Ukraine, Politico Europe reported on Tuesday, citing diplomatic sources.

Rutte reportedly raised the issue during a closed door meeting of NATO ambassadors late last month. If adopted, the proposal, first floated by Ukrainian leader Vladimir Zelensky last year, would effectively triple aid to Kiev to around $143 billion annually, according to NATO estimates of the allies' combined GDP cited by Politico.

The proposal is said to be partly motivated by frustration among some countries that they are contributing more support to Ukraine than others. Several allies, including major NATO members France and Britain, reportedly oppose the initiative.

The discussions on increasing support for cash-strapped Ukraine come as the country has been rocked by another major corruption scandal allegedly involving figures close to Zelensky.

On Thursday, Ukraine's top anti-corruption court is expected to rule on whether to detain Zelensky's former chief of staff, Andrey Yermak, who was named a suspect in a money laundering case involving kickbacks in the energy sector and elite real estate developments outside Kiev. According to the Western-backed National Anti-Corruption Bureau of Ukraine (NABU), the suspects, including former Deputy Prime Minister Aleksey Chernyshov, laundered around $9 million through investments in the construction of the Dinastia (Dynasty) residential complex.

Last year, investigators uncovered a $100 million kickback scheme allegedly orchestrated by Timur Mindich, Zelensky's longtime former business partner, who has been described in the media as his "wallet." Mindich fled the country to avoid arrest, while several senior officials, including two ministers, resigned.
