How splits on the right may threaten Poland’s pro-European camp

Problem

Poland’s party system is unravelling. The Law and Justice (PiS) party, led by Jaroslaw Kaczyński, has split. More than 40 of its members have formed a separate parliamentary caucus that includes Mateusz Morawiecki, prime minister for most of the party’s rule from 2015 to 2023. This ends an era of over 20 years that has been shaped by two powerful men and their parties: Kaczynski’s right-wing nationalist, Eurosceptic PiS and Donald Tusk’s liberal-conservative, pro-European Civic Coalition (KO).

At first glance, the collapse of his old enemy is a gift to Tusk. KO leads with 29%; PiS has slipped below 19% since the split. Four groupings now compete on the right, and Poland’s voting system punishes fragmentation, so four medium-sized parties win fewer seats than one large party on the same vote.

However, Morawiecki broke away in protest at PiS’s radicalisation, hoping to win over the very centre-right voters who helped return Tusk to power in 2023 after eight years of PiS rule. Most are now disillusioned (Tusk’s government has dismal approval ratings), politically homeless and angry. If they split their vote among the four right-wing parties or stay at home, Tusk may meet the same fate as Kaczynski in 2023: he could win the election in 2027 but be unable to assemble a majority coalition.

The other problem is one of method. For two decades Tusk has, often successfully, run against Kaczynski rather than on a programme of his own. Polarisation served both men well: each could rally his own voters by invoking the threat of the other, and smaller parties were squeezed out. Kaczynski’s decline forces Tusk to find another way to win.

Solution

Rather than betting on his enemy’s demise, Tusk should proactively set the agenda and win centrists beyond his base, as in 2023. Economic and social questions will matter, but foreign policy is set to loom unusually large in next year’s campaign. A record 25% of Poles favour leaving the EU (“Polexit”), hostility to Ukraine is rising and the right-wing parties are competing to outdo one another in anti-EU, anti-German and xenophobic rhetoric.

Tusk, a risk-averse tactician, has long avoided confrontation on those fundamental issues, calculating that exposing himself to attack from the right would be self-defeating. The far-right, however, has filled that vacuum, for example through its campaign against SAFE, the EU’s defence-loan scheme, and in the hardening mood towards Ukraine.

A more volatile party system may paradoxically make anti-Tusk majorities easier to build. That is an argument for the leader of Poland’s pro-European camp to take up the fight rather than duck it. Tusk needs to explain to Polish voters, more forcefully than before, why the EU is the best response to pressure from Donald Trump and Russia; why anchoring Ukraine in Europe is a Polish raison d’état; and how Poland’s interests differ from those the nationalists describe.

Context

Poles vote for a new parliament in October 2027. Tusk’s five-party coalition faces an uphill struggle to stay in office. The coalition partners have weak support or may not be able to re-enter the government at all.

Recent polls give the four right-wing parties a majority between them; whether their rivalries would allow a coalition is another matter. PiS has moved further right in recent months to stop core voters defecting to more radical rivals, in a shift which provoked Morawiecki’s rebellion. His departure will probably set off further political realignments before the 2027 election.
