Dag Seierstad

Dag Seierstad (5 August 1936 to 8 October 2026) was a Norwegian socialist politician, writer and public debater who spent close to seven decades at the centre of the campaign against Norwegian membership of the European Community and the European Union. To friends and opponents alike he was the man who knew the treaties best.

He grew up in Bjølsen in Oslo and trained as a physicist, taking the cand.real. degree. Politics, not physics, became his life's work. He joined the Socialist Student Association (Sosialistisk Studentlag) in 1958 and was a member of the Socialist People's Party (SF) from its founding in 1961. He sat on SF's central board in the late 1960s and early 1970s and led the party's EEC committee. A study circle booklet he wrote on the EEC was printed in 7,000 copies before it became the Pax book "EF eller Norge?" in 1972, the year Norwegians first voted no to membership.

When SF became part of the Socialist Left Party (SV), Seierstad stayed at its core. He sat on SV's central board from 1995 to 2005 and was the party's lead candidate in Oppland at the Storting elections of 1993 and 1997. For many years he also worked as an amanuensis (associate lecturer) in social policy at Lillehammer University College, and Lillehammer became his home.

His greatest influence came through the No to EU movement (Nei til EU). He sat on its board from 1990 to 1995, led Oppland No to EU from 1991 to 1994 and again for many years after 2000, worked as the organisation's analyst from 1995 to 2003 and later returned to its board and council. He wrote more than 1,000 weekly columns on the EU, first in Ny Tid, then in Nationen and finally in Klassekampen. A 2006 festschrift noted some 2,700 pages written or edited by him in the national library catalogue, and in 2014 he wrote "Folket sa nei", a history of Norwegian resistance to the EU.

Seierstad was a key critical voice around the 2012 Europe Committee report (NOU) on Norway's agreements with the EU, was central to the 2012 Alternative Report that reshaped the trade union debate on the EEA agreement, and in 2017 was the main author of No to EU's own EEA report. His gift for unpicking complex directives and explaining what they meant for working people made him a trusted source in the labour movement.

Honours followed. In 2006 he received Klassekampen's cultural prize, Neshornet, for his long and tireless work for the Norwegian left. In 2012 No to EU made him its first ever honorary member, an honour he himself protested as unnecessary. In 2020 he received the honorary award of the Trondheim Conference, and No to EU created the Seierstad scholarship for master's students writing about EU and EEA questions.

He was married to Frøydis Guldahl and was the father of Åsne, Tori and Taral Seierstad. His daughter Åsne Seierstad became one of Norway's best known journalists and authors.

Dag Seierstad died at the hospital in Lillehammer on 8 October 2026, aged 90, after five days as a patient there, with his wife at his side. Colleagues remembered a mild, humorous and generous man who spoke respectfully of those he disagreed with and who built broad alliances across party lines. As No to EU put it, the word many people connect with Dag Seierstad is knowledge.
