My friend Bill Bradbury, who has died of cancer aged 73, was a long-term and prolific writer of letters to the Guardian. They were always leftwing and mostly moral in nature, but leavened by his acerbic wit.
As a teacher and headteacher for nearly 40 years, he was highly committed to his special needs pupils and he led two schools. Bill rapidly improved the first, Samuel Laycock school in Tameside, Greater Manchester, and achieved a perfect “outstanding in all areas” from Ofsted at the second, Rumworth school in Bolton. In recognition of this he was appointed a national leader in education in 2007.
