This support is an interest-free loan designed to meet Ukraine's military and economic needs over the next two years.
Ukrainian President Volodymyr Zelensky thanked EU leaders, stating the "significant" investment would strengthen the country's resilience and provide financial security.
The agreement was reached after EU leaders reassured Belgium regarding potential Russian retaliation, and it avoids directly using frozen Russian assets for the loan.
The UK government indicated its willingness to share the risk to unlock frozen Russian assets for Ukraine, with Defence Minister Luke Pollard also urging Roman Abramovich to release £2.5 billion from the Chelsea sale for the country.
