Staffan de Mistura and the Stalled UN Mediation
A Veteran Diplomat Takes the File
The UN Secretary-General appointed Staffan de Mistura of Italy as Personal Envoy for Western Sahara in October 2021. A seasoned mediator whose past assignments included Syria and Afghanistan, he inherited a process that had been without an envoy for more than two years.
His mandate is to facilitate a mutually acceptable political solution through the so-called roundtable format, which brings together Morocco, the Polisario, Algeria and Mauritania. Progress has been minimal, with the parties locked in fundamentally opposed positions on sovereignty versus self-determination.
Frustration and a Resignation Signal
In October 2024, de Mistura signalled to the Security Council that he might step down within roughly six months, acknowledging the limits of his mediation. He even floated difficult questions about the future of the UN's decades-old presence on the ground.
By April 2025, however, his tone shifted. He urged the Council to capitalize on a changed international context increasingly favourable to Morocco's autonomy plan, driven by US and French backing, and called the following three months crucial for charting a roadmap toward a durable settlement.
Pressing Morocco to Detail Autonomy
De Mistura has repeatedly asked Morocco to flesh out its 2007 autonomy initiative, telling the Council that members and supporting states have a right to know precisely what powers would be devolved.
To illustrate, he cited working autonomy arrangements such as Scotland, Greenland and South Tyrol, noting pointedly that the autonomy enjoyed by South Tyrol is significantly broader than what Morocco has so far offered, an implicit invitation to Rabat to go further.
Algeria's Role in the Talks
A recurring theme of de Mistura's tenure is the centrality of Algeria. In September 2025 he publicly refuted Algiers' claim that it is merely an observer, reinforcing the view that no settlement is possible without Algeria's direct engagement.
His mediation thus reframes the dispute as a regional file requiring all four roundtable participants, rather than a bilateral negotiation between Morocco and a movement it regards as Algerian-backed.
