Polish support for fast-tracking Ukraine into the EU drops from 60% to 9%

Fact-check index: 55/100 — The core polling statistic (9% vs 60%) and the characterization of worsening Polish-Ukrainian relations are directly supported by the iDNES.cz source, but most surrounding context, causal explanations, and the EU unanimity claim are not found in the brief source material and are presented as unsourced background or labeled speculation.

• Polish support for fast-tracking Ukraine's EU accession has fallen to 9%, from 60% before the February 2022 invasion — Directly matches source: 'jen devět procent Poláků je pro rychlé přijetí Ukrajiny do EU. Před ruskou invazí jich bylo šedesát procent,' with iDNES.cz cited.
• Polish-Ukrainian relations are deteriorating further — Matches source lede: 'Vztahy Polska a Ukrajiny jsou na tom pořád hůř.'
• Poland has been Ukraine's most forceful EU advocate since 2022, taking in millions of refugees, pushing weapons deliveries and lobbying hardest for Kyiv's membership — Plausible well-known background, but not stated anywhere in the single short source provided; no citation given for these specifics.
• Unanimity among all 27 EU member states is required to admit any new country — General EU accession fact not mentioned in the source material; presented without citation.
• The erosion reflects friction over Ukrainian grain imports and refugee costs rather than reversed hostility toward Russia — Explicitly labeled a 'Hypothesis' by the article itself, and the article concedes the source gives no breakdown of reasons — appropriately flagged as interpretation, not established fact.
• Polish-Ukrainian tension over agricultural trade has run alongside military solidarity for years — Used as supporting context for the hypothesis but not contained in or supported by the cited source.
• A unified Western front deterring Moscow loses a key constituency if Poland can't rally support for accession — Analytical/opinion claim extrapolated by the article, not a factual assertion from the source.
• Watch whether Warsaw hardens its stance at EU summits, and whether Slovakia or the Baltic states show similar erosion — Forward-looking speculation with no basis in the cited source, which contains no mention of summits, Slovakia, or the Baltic states.
