The EU froze funds earmarked for Hungary and Poland over their nationalist governments' track record of undercutting liberal democratic rules.
Portugal had disbursed 1.4 billion euros, or 8.5% of the total recovery funds assigned to it, to project promoters by the end of 2022.
Romania and Portugal are the two countries pushing hardest to extend the 2026 deadline and Spain and other Eastern European countries are supporting their demands, a source with knowledge of the negotiations said.
Some countries are devising workarounds for projects that are particularly important and look like they are unlikely to meet the deadline, said a source.
This would imply budgeting and allocating funds before the projects have been commissioned in order to meet the 2026 deadline, the person said.
