Hungary has lifted its two-year-long veto on Ukraine's bid to join the European Union, allowing the process to enter its next phase of negotiations and ending a political saga that sent relations between Budapest and Kyiv to an all-time low.

The sought-after breakthrough took place suddenly on Wednesday evening during a meeting of ambassadors in Brussels, several diplomats confirmed to Euronews.

The Hungarian envoy signalled the lifting of the reservations, allowing the 27 member states to reach the necessary unanimity to initiate the talks.

Accession consists of 33 chapters split into six thematic clusters.

The first cluster, known as fundamentals because it covers the rule of law, human rights and the judiciary, is the first and last to be opened in the complex process.
