Greenland's anti-Trump foreign minister quits own party after Siumut exits government

• Motzfeldt told Sermitsiaq that Siumut's leadership had effectively declared her government work unnecessary
• Siumut now holds just three seats in the Inatsisartut, down from ten four years ago
• Motzfeldt lost the party chairmanship to Aleqa Hammond in June before the latest rupture
• Greenland's most prominent voice against Trump's territorial ambitions is now politically unmoored

Vivian Motzfeldt, the Greenlandic foreign minister who emerged as the territory's sharpest public critic of Donald Trump's annexation rhetoric, has quit the Siumut party after its leadership pulled out of the governing coalition over the weekend. The move cost Motzfeldt her cabinet seat. RÚV reports that Motzfeldt told the Greenlandic newspaper Sermitsiaq she saw no reason to remain in a party that had shut itself out of political power. The party's leadership, she said, had effectively decided that her work in government was unnecessary.

"I am in politics to have influence and to contribute to society," Motzfeldt told Sermitsiaq. By walking out of the coalition, Siumut's leaders made that impossible.

The departure caps a brutal stretch for what was once Greenland's dominant political force. Siumut won just four seats in last year's elections to the Inatsisartut (Greenland's parliament), down from ten four years earlier. Party leader Erik Jensen resigned after the result. Motzfeldt stepped in as acting chair, only to lose the subsequent leadership contest to Aleqa Hammond in June. Now, with Motzfeldt gone, Siumut holds three seats — a rump faction with no government role and no obvious path back to relevance.

The timing matters beyond Greenlandic domestic politics. Motzfeldt had become the most recognisable Greenlandic voice rejecting Washington's pressure campaign. When Trump revived talk of purchasing or otherwise absorbing Greenland, it was Motzfeldt who delivered Nuuk's response to international media. Her political marginalisation — engineered not by American pressure but by her own party's internal manoeuvring — removes the person most associated with that defiance from any position of authority.

Greenland's post-election political landscape is fragmented, with multiple small parties jockeying inside a coalition government that now has one fewer partner. The question of who speaks for Greenland on sovereignty and foreign affairs — the issues that have drawn global attention to an island of 57,000 people — is suddenly open. Motzfeldt built international credibility on the file. Whoever replaces her at the foreign affairs desk inherits the portfolio without the profile.

Siumut, founded in 1977 and the party that governed Greenland for most of the home rule era, now sits in opposition with fewer parliamentarians than some parties founded in the last decade. Motzfeldt says she intends to remain in politics. Siumut's remaining three members intend the same, though the audience is shrinking.
