The Princess of Wales has invited families affected by the Southport attacks to her annual Christmas carol service, Kensington Palace has said.
The fourth Together At Christmas service will take place at Westminster Abbey on 6 December.
The event will come at the end of a year during which Catherine has had to largely withdraw from public duties following her cancer diagnosis.
Last month, she visited Southport with the Prince of Wales where they held a private meeting with the bereaved families of three children killed in the knife attack in July, in what was her first official public engagement since she finished chemotherapy treatment.
