Many fights lie ahead for European Union countries before they can reach unanimous agreement on the proposed 1.85 trillion euros worth of spending through their next joint budget and a new coronavirus economic recovery scheme.

The new stimulus plan worth 750 billion euros would add to the 2021-27 EU budget. Talks on the latter stalled even before the pandemic, amid rifts between net payers and beneficiaries.

Here are the main fault lines that need to be resolved for there to be a deal, and potential trade-offs.

SIZE AND HOW TO RAISE IT

The EU executive wants to set the bloc's next budget at 1.1 trillion euros and top it up with 750 billion euros worth of new stimulus money, which the European Commission itself would borrow on the market against the budget and national guarantees.

Northern members including Denmark and the Netherlands want to trim the budget. Germany backs them in opposing raising joint debt, while the south and east call for unprecedented spending.

GRANTS OR LOANS

The vast majority of the total 1.85 trillion euros would be doled out in free grants, as sought by ailing southerners Spain and Italy, as well as France.

But a club of frugal states - Austria, the Netherlands, Denmark and Finland - strongly prefers repayable loans, in order to help their peers but avoid bankrolling those they see as fiscally reckless.

REBATES

One idea to get the "Frugals" on board is to let them keep their current rebates in the next budget, a demand also put forward by Germany - the biggest contributor to the bloc's joint coffers.

European Commission and other countries earlier pushed to end that practice after Brexit removed from the picture "the mother of all rebates" in the bloc.

CONDITIONS

The more goes out in grants, the more the "Frugals" will call for conditions attached to the money, including macroeconomic reforms. That is opposed by southern states reeling from the coronavirus crisis and demanding unrestrained aid.

Governments in Poland and Hungary - accused by the EU and rights organisations of undercutting democracy at home - want to evade strict rule of law conditions on accessing EU funds. Their wealthier, western peers say those are indispensable to safeguard the bloc's core values.

HOW TO SPEND IT

The bloc needs to agree on how the money from the budget and the stimulus scheme is allocated between member states and key policy areas.

Northerners want to spend on green investment and innovations, France and Poland to uphold massive farm subsidies, poorer peripheral regions to keep their generous development benefits, while those hardest-hit by the coronavirus cry for help.

NET PAYERS AND BENEFICIARIES

The proposed recovery scheme is designed to allow countries that are poorer or already in debt, like Italy, to get extra financing without aggravating their fiscal problems.

But Commission borrowing will have to be repaid, which would put bigger strain on richer states including Germany, Sweden or Luxembourg.
