19:50 UPDATE
Coach has returned. All safe and well. Thank you to staff, pupils and parents for their patience.
18:50 UPDATE
The coach has made good time, passing through Petersfield at 18:45. We hope it will therefore arrive at Springfield at approx. 19:15.
Unfortunately, the coach company has had to send an alternative coach to collect the pupils from Chessington. This is due to an apparent issue with the driver's key. This has resulted in a delay to departure. Pupils are now expected to return to school at approximately 8pm. Please keep checking the website for details. (All pupils safe and well - no cause for concern.)
