Discovery New School in Crawley, West Sussex, is due to close its doors today amid concerns about the standard of education it offered - it is the first time this kind of action has been taken.
The school has around 70 pupils who will all have to find new schools.

"We were trying to do something very different here and always looking for short-term measures and quick results doesn't always produce what you want."
