The decision of whether Prue Leith should continue presenting The Great British Bake Off is entirely up to the producers, broadcasters, and stakeholders involved in the show.
Prue Leith was one of the judges on The Great British Bake Off, alongside Paul Hollywood. Her presence on the show has been well-received by audiences and critics alike. However, circumstances can change, and decisions about the show's lineup may be subject to various factors, such as contractual agreements, audience feedback, and the preferences of the show's creators and hosts.
If you're looking for the most up-to-date information on the show and its cast, I recommend checking official sources, such as the show's website or reputable entertainment news outlets, to see if there have been any recent announcements or developments regarding Prue Leith's involvement.
