European Athletics president Svein Arne Hansen has died at the age of 74.
Norwegian Hansen, first elected president in 2015, died in Oslo on Saturday after failing to recover from a stroke he suffered in March.
Interim president Dobromir Karamarinov said Hansen was a "great leader, a visionary and a charismatic personality within the athletics family".
He added: "Above all he was a friend of the athletes. We have lost a great man."
