Volodymyr Zelensky has promised to reverse a crackdown on Ukraine’s anticorruption agencies following street protests.

Thousands of people gathered in the streets of Kyiv, Ukraine, on Tuesday night to protest moves by President Volodymyr Zelensky’s government to weaken anticorruption institutions, in the country’s first major antigovernment demonstration in three and a half years of war.

Fighting entrenched corruption is crucial for Ukraine’s aspirations to join the EU and maintain access to billions of dollars in western aid.
