"Mr Oliver will be different to me, will do things differently. He will be able to see with fresh eyes what needs to change and develop here. Please support him."

"From mid-June, I will be working part-time for Interlead, supporting secondary principals, and at the same time I will carry out educational consultancy. Whatever I'm doing, I hope to be making a difference for schools and to young people," Mr Hensman says.

"The predominant emotion for me over the last months has been a deep sorrow. I would love to have kept leading the staff and students on the road we've been travelling in recent years."
