John Leeson, the British actor who gave voice to K9, the robot dog companion of Doctor Who, has died at the age of 83, his family has confirmed. Fans of the long-running BBC science fiction series knew him as the distinctive voice of one of the show's most beloved characters.

In a Facebook post, Leeson's son, Guy Ducker, announced the death of his father, who was known professionally as John Leeson and whose legal name was John Ducker. Ducker wrote that his father died at 3:03 p.m. after a summer of illness. The family did not provide further details about the cause of death in the statement.

Leeson's work on the series made K9 one of the most recognizable non-human characters in the franchise. The robot dog, a metal companion to the Doctor, was voiced by Leeson, whose voice became inseparable from the character's dry, mechanical delivery. The role made him a familiar presence to generations of viewers who followed the Doctor's travels through time and space.

The announcement drew attention from the wider entertainment world, where colleagues and fans marked the loss of an actor whose contribution to a popular British television institution remained widely remembered. Leeson's voice work ensured that K9 remained a fixed point of the show's identity across its many decades on screen.

Leeson was English by nationality and built a career in British acting, though the coverage of his death focuses above all on his association with Doctor Who. His family's post, which confirmed the death on the day it occurred, was the primary source of the news.
