LONDON (AP) _ Princess Diana's charity work will be honored Dec. 1 with a candlelight procession and vigil on World AIDS Day.

Film producer David Puttnam will speak during the event, dubbed the ``Celebration of Life'' by the sponsor, the National AIDS Trust.

Hundreds of people are expected to gather at Green Park in London, then walk along Piccadilly and arrive at St. James's Church, where the vigil will take place.

```Celebration of Life' will give people a chance to look back and remember Princess Diana's life and work on AIDS, and the many lives that have been lost to the disease,'' trust director Derek Bodell said.

Diana, who died in a Paris car wreck on Aug. 31, was a patron of the trust and worked hard to highlight the plight of AIDS sufferers.
