On Monday 22 February, The King took part in Stockholm International Peace Research Institute's (SIPRI's) 50th anniversary celebrations.
The celebrations began at SIPRI's head office in Solna, where Chairman Sven-Olof Petersson and Director Dan Smith welcomed those present.
The King then gave a speech, in which he spoke about SIPRI's role in an increasingly complex world where policymakers need to base their decisions on facts from objective sources. He added that SIPRI is such a source, and this is what has made SIPRI so successful.

It is an independent research institute that studies armed conflict, armaments, arms control and disarmament. SIPRI provides data, analysis and recommendations, based on open sources, to policymakers, researchers, media and the interested public. The institute has an international board.
