Two of Volodymyr Zelensky's close allies have stood down amid a multi-million-pound corruption scandal.
Justice Minister German Galushchenko and Energy Minister Svitlana Hrynchuk resigned on Wednesday as part of a £76million sleaze scandal in Ukraine's energy sector.
This week, officers from Ukraine's National Anti-Corruption Bureau (Nabu) raided the homes of Mr Galushchenko and fellow Zelensky ally Timur Mindich as part of a 15-month operation which has included 70 searches.
Nabu later posted photos which showed bags full of dollars and euros, however it is not known where this had been taken from.
Mr Zelensky had earlier demanded their resignations, warning that the pair "cannot remain in their positions".
"Right now it is extremely difficult for everyone in Ukraine - enduring power outages, Russian strikes, and losses.
"It is absolutely unacceptable that amid all this there are also some schemes in the energy sector."
He added: "There must be maximum integrity in the energy sector, in absolutely all processes.

"I support - and the Prime Minister supports - every investigation carried out by law enforcement and anti-corruption officials."
Investigators have alleged that Mr Galushchenko was part of a scheme to secure kickbacks from the energy sector orchestrated by Mr Mindich.
The Specialised Anti-Corruption Prosecutor's Office alleged that the former Justice Minister received "personal benefits" from Mr Mindich in exchange for control over funds within the energy sector.
But Ms Hrynchuk was not named amongst those who profited from the scheme by investigators or prosecutors.

She has not been charged in the case, and neither has Mr Galushchenko, with both of them denying any wrongdoing.
So far, seven people have been charged in relation to the scheme.
Mr Mindich is believed to have fled abroad just hours before authorities went to search his apartment in Kyiv this week.
He is the co-owner of the media company Kvartal 95 which was founded by Mr Zelensky, and the two have been friends for years.

Although the President has not yet commented on Mr Mindich's part in the scheme, the Prime Minister, Yulia Svyrydenko confirmed personal sanctions against Mr Mindich and Oleksandr Tsukerman, another businessman charged.
The country's national anti-corruption bureau said several people had created a "criminal gang" which built "a large-scale corruption scheme to influence strategic enterprises in the public sector, in particular Energoatom", Ukraine's nuclear energy agency.
Corruption within the energy sector is a particularly sensitive topic in Ukraine at the moment as the country faces daily power cuts due to Russian attacks on national energy sites.
Earlier on Wednesday Ms Svyrydenko confirmed Mr Galushchenko had been suspended from his position, but he said he will continue to defend himself and "prove" his position.
