Suppose, you are the President of BELTA. The teacher training programme has already been over nominated and you have to regret a large number of teachers. Now, write such a regret letter in reply to an e-mail message for such a request.

Subject: Ref. Teacher Training Programme
Dear Ms Suraiya,
Thank you very much for your interest in our teacher training programme. I am very sorry to inform you that our programme has been over subscribed and we have already regretted 125 nominations. You are the 126th teacher to be regretted now. We have already talked to the donor agencies to provide us fund for such trainings in future. So, we are keeping your name on our list for future training. I hope we would meet very soon.
With regards,
S. Zaman
