1988 Ebbe Carlsson Affair

On 1 June 1988 Expressen revealed that the publisher Ebbe Carlsson had been conducting an unauthorised parallel investigation into the 1986 Palme assassination, pursuing the “Kurdish track” theory then circulating in security circles. Carlsson operated with the secret backing of Justice Minister Anna-Greta Leijon, mentored by former minister Carl Lidbom, and with operational assistance from rogue elements within SÄPO. The exposure was triggered when Swedish customs at Helsingborg intercepted a Carlsson contact smuggling wiretapping equipment into the country.

A constitutional and political crisis followed within days. Anna-Greta Leijon resigned a week after the exposure. The affair was one of the gravest constitutional and intelligence-service scandals of the post-war era: a sitting Justice Minister had given informal backing to an extra-legal investigation involving illegal wiretap equipment and SÄPO personnel acting outside their formal mandate.

The Ebbe Carlsson affair exposed the institutional aftershocks of the Palme murder — a state apparatus that had failed to solve the assassination had produced parallel structures attempting to do so — and damaged the political credibility of the post-Palme Carlsson SAP government less than five months before the 1988 Riksdag election. It catalysed the late-1980s public confidence crisis that fed into the 1991 SAP electoral defeat and embedded a permanent suspicion of “old-boys” networks in Swedish security politics that recurred in later journalistic and parliamentary inquiries into SÄPO.
