Dame Esther Rantzen urged assisted dying campaigners to carry on in a note written before her death, her family has revealed.

The broadcaster and Childline founder said she had felt unable to choose how she would die and intended to support the campaign even after her death. She had become an advocate for legalising assisted dying after being diagnosed with stage four lung cancer.

Rantzen died last month at her home in the New Forest, aged 86. Her family announced that they had attended a small, private funeral last week. Her daughter, Rebecca Wilcox, described it as beautiful and said messages of sympathy from around the world had brought the family comfort.

A larger memorial service is expected at a later date, though details have not been announced.
