Member states are currently weighing how to cut costs as part of a wider agreement, under which the European Commission, European Parliament and Council of the EU could all see their budgets shrink.

EU countries are locked in intense negotiations on the next Multiannual Financial Framework (MFF), the budget for 2028-2034. On Wednesday, ambassadors will discuss potential landing zones for the total volume, originally set at around €2 trillion.

"A majority of member states saw Heading 4 [European Public Administration] as an area where reductions could be made," reads a note circulated ahead of a discussion at EU ambassador level on Wednesday and seen by Euronews.

According to the document, many European governments questioned "the justification of the proposed increase in staff levels contained in the Commission proposal while many member states are constraining expenditure and headcount in their own national civil services".

How high Brussels should set the bar for the next budget remains a point of contention between member states, split into a camp calling for a more ambitious budget led by France and Spain, and the so-called "frugals", like Germany and the Netherlands, who want to reduce it by "several hundred billion euros."

In June, the Cypriot rotating presidency of the EU Council presented a compromise proposal reducing the overall size by 2%, with the heftiest cuts falling on the Competitiveness Fund, for defense and industry investments, and the Global Europe Fund, the development aid pot.

The current Irish presidency is now working on a new compromise, expected in early October, ahead of a fresh discussion at the European Council summit on October 15-16.

"What is your view on the volume of expenditure proposed by the current Negotiating Box and what do you see as the potential landing zone for these discussions?" the Irish government asked EU ambassadors in the note.

On funding for National and Regional Partnership Plans, which cover EU support for poorer regions, agriculture and fisheries, the note states that it "is the most important priority for the majority of member states".

On the Competitiveness Fund, the presidency acknowledges broad support for its objectives of boosting Europe's research and defense industries, but notes "there is a degree of openness by some to more moderated increases".

Enlargement support, particularly for Ukraine, is also seen as a priority within the international aid programme.

In other words, the area of broadest consensus, according to the presidency note, is the budget allocated to the EU institutions themselves. Many European capitals are already tightening their belts, squeezed by ballooning defense spending, rising energy costs and aid to Ukraine.

The European Commission is already undergoing a review expected to lead to an internal reorganization. Those plans could be coupled with a proposal on how to make a union of 30 or more member states work in practice, expected at the end of the month.

The European External Action Service is also under pressure to reform and become more effective, with the latest German-led proposal suggesting the EU's diplomatic service could be placed directly under the Commission's remit, with a significant presence of seconded national diplomats.

The discussion on the bloc's budget will continue at a meeting of the General Affairs Council next week.
