We chat to author Sathnam Sanghera about his school days and the teachers that inspired him, including:

• How his English teacher changed the course of his life.
• The problems he faced in his PE lessons.
• A love of practical jokes - including one on a school trip that didn't go down well.
• Developing a side business in selling his packed lunches.
• Introducing pupils in school to a more detailed history of colonialism.
