Princess Kate is set to make her most prominent return to royal life as host of the annual Christmas carol service at London's Westminster Abbey.

Royal family members will show up for Princess Kate at her annual Christmas carol service, Kensington Palace confirmed.

The Princess of Wales is making a steady return to royal duties following what has been one of the most tumultuous years of her life. In March, Kate confirmed she had been diagnosed with an unknown form of cancer.

Kate wore her famed sapphire engagement ring during a slate of engagements for the annual Festival of Remembrance.

The princess has begun to return to some public duties since finishing chemotherapy in September.

Kate, Britain's Princess of Wales, will make her most prominent return to royal engagements since having treatment for cancer next month when she hosts an annual Christmas carol service at London's Westminster Abbey.
