Elizabeth Sladen, the Doctor's famous travelling companion Sarah Jane, who left BBC series Doctor Who, (then played by Tom Baker), in 1976 - then returned for follow up progs The School Reunion and The Sarah Jane Adventures, has sadly died of cancer, aged 63.
This is a very poignant moment from 'The School Reunion' which starred David Tennant and Billie Piper, along with Elizabeth.
Goodbye My Sarah Jane
