Veteran British actress Jane Asher is to make a guest appearance on BBC One's The Sarah Jane Adventures.

The Doctor Who spin-off, featuring Elisabeth Sladen in the title role, will feature actress and celebrity chef Asher in a one-off role, according to The Sun.

This is not Asher's first brush with the cult show, as she portrayed the character of Susan Foreman - The Doctor's granddaughter - in a radio play entitled Whatever Happened To Susan Foreman? in 1994. She will soon be seen in the British comedy film Death at a Funeral.

The Sarah Jane Adventures is set to form part of the CBBC Autumn schedule.
