His voice would have fit well in this world we live in, says current Social Democratic leader Magdalena Andersson.
He was known for standing up to great powers that wanted to dominate other countries.
Andersson laid a wreath at Adolf Fredrik's grave in Stockholm together with Ingvar Carlsson, who succeeded Palme as Prime Minister.
For the first time, all other living former Social Democratic leaders were also present.
It was nice to meet them, and it was also fun, Andersson says.
She believes that the likelihood the murder will one day be solved is not very high.
Andersson recalls that the murder was preceded by an intense hate campaign against Palme.
If there is any lesson we should learn, it is to always speak respectfully about each other, she says.
