Siumut has left Greenland’s coalition government, opening a new political crisis in Nuuk just as Greenland is trying to project unity under renewed pressure from the USA. The party’s withdrawal weakens the broad coalition led by Prime Minister (formanden for Naalakkersuisut) Jens-Frederik Nielsen, but it does not bring down the government: the remaining parties still hold a majority in Inatsisartut, Greenland’s parliament.
Why Siumut walked out of the coalition
Siumut announced on 13 March that it was leaving the four-party coalition after a dispute over two serving ministers who had entered the campaign for Denmark’s parliamentary election. The immediate trigger was the candidacy of Anna Wangenheim, Minister for Health and Persons with Disabilities (naalakkersuisoq for sundhed og personer med handicap), and Naaja H. Nathanielsen, Minister for Equality, Justice and Raw Materials (naalakkersuisoq for ligestilling, justits og råstoffer).
Party leader Aleqa Hammond argued that the coalition could no longer function because the parties had become too politically distant and insufficiently coordinated. She also criticised what she described as weak leadership and an incomplete government structure. The dispute had been building for days, but the final decision came quickly and turned an internal disagreement into a broader crisis for Greenlandic politics.
The timing matters. Greenland is due to elect its two representatives to Denmark’s Folketing later this month, and the dispute has erupted at a moment when domestic political divisions are under closer international scrutiny than usual.
Why the government still has a majority
For all the political drama, Siumut’s exit does not collapse the government. The party held four seats, and after its departure the coalition formed by Demokraatit, Inuit Ataqatigiit and Atassut still controls 19 of Inatsisartut’s 31 seats. That is comfortably above the 16 needed for a majority.
This means Jens-Frederik Nielsen can continue in office without immediately rebuilding the coalition. Even so, the political cost is real. The government was originally designed as a broad alliance after the 2025 election, when Greenland’s main parties chose a wide parliamentary arrangement that excluded only Naleraq. At the time, that coalition was also meant to signal internal stability as Greenland faced a more confrontational tone from Washington.
Siumut’s departure therefore matters less for the arithmetic of power than for the message it sends. The coalition survives, but it no longer looks as politically unified as it did when it was formed.
Vivian Motzfeldt’s departure adds to the fallout
One of the most significant immediate consequences is the exit of Vivian Motzfeldt, who stepped down as Minister for Foreign Affairs and Research (naalakkersuisoq for udenrigsanliggender og forskning) after Siumut left the coalition. Her departure is especially sensitive because she had become one of Greenland’s most visible international figures in recent months.
Motzfeldt had been directly involved in contacts with the USA during the latest phase of tension over Greenland, including the January meeting in Washington with Danish Foreign Minister Lars Løkke Rasmussen, Secretary of State Marco Rubio and Vice President J.D. Vance. That meeting led to the creation of a working group at official level, intended to manage the diplomatic crisis.
After leaving government, Motzfeldt also said she disagreed with Siumut’s decision and later left the party itself. She has signalled that she wants to remain part of the political solution rather than move to the sidelines, a message that underlines how divisive the break has become even inside Siumut.
A historic party in a deeper crisis
The rupture is particularly striking because Siumut is not a marginal actor in Greenlandic politics. It is one of the island’s main historic parties and has been central to the development of modern self-government for decades. But its authority has weakened sharply over the past year.
At the 2025 election, Siumut suffered its worst result in modern Greenlandic politics, winning only four seats. The party then entered the broad coalition anyway, a choice that was always likely to remain fragile after Aleqa Hammond returned to the leadership. Her line has now prevailed, but at the price of deepening the party’s internal crisis and pushing some of its most recognisable figures away.
Why this matters beyond Nuuk
This crisis is not just another coalition dispute. It comes while Greenland is dealing with unusually direct geopolitical pressure, above all from repeated statements by Donald Trump about bringing the island under USA control. In that context, Jens-Frederik Nielsen had argued that political unity was a strategic necessity, not simply a matter of good coalition management.
That is why the break has resonated beyond day-to-day parliamentary politics. It affects Greenland’s external credibility, the handling of relations with Copenhagen and Washington, and the domestic debate on how the island should defend its autonomy while continuing its long-term discussion about independence.
The government remains in place, and the numbers in parliament still favour Nielsen. But Greenland now faces an awkward mix of institutional continuity and political fragmentation. For a country that has spent the past year trying to show calm and coherence under international pressure, that is a serious setback.
