As of my last knowledge update in October 2021, Gillian Leggat does not appear to be a widely recognized author or public figure. It is possible that you are referring to a lesser-known writer or someone who has gained prominence after that date.
If you can provide more context or clarify which Gillian Leggat you are referring to (such as specific works or achievements), I would be glad to help to the best of my ability. Otherwise, I recommend checking recent sources or news articles for the most current information.
