While the statement "I now request the committee members to kindly escort our chief guest back to his chair" is polite, it might come across as a bit direct or abrupt. When asking the chief guest to leave the stage and join the audience, it's essential to use language that conveys respect and appreciation for their presence while also making them feel comfortable with the transition. Here's a suggested phrasing:
"Ladies and gentlemen, we are incredibly honored to have our esteemed chief guest grace this event with their presence. We sincerely thank them for their valuable time and inspiring words. As the program continues, we kindly request our chief guest to take a seat amongst our esteemed audience, so they may enjoy the rest of the event from there. Thank you once again for your gracious presence."
By using phrases like "esteemed chief guest," "sincerely thank them," and expressing gratitude, the request sounds more appreciative and respectful. Also, the emphasis on the chief guest being able to enjoy the rest of the event with the audience helps in making the request sound more welcoming.
