In the past, Mr McIntosh could always be relied on to predict dire consequences when politicians dare to consider the abolition of grant-maintained status for schools. In some circles, he is even credited with inventing the idea at a Number Ten seminar during the Thatcher era, and his own school was one of the first to opt out of local authority control.
These days, he says, any ear-bashing of the Prime Minister that he manages at parents' evening is about the amount of paperwork that lands on his desk as a result of Mr Blair's Government initiatives on education. The avalanche of documents makes his heart sink more than the thought of the imminent arrival of two governors appointed by Labour-controlled Hammersmith and Fulham.
The problem, he says, is that it takes valuable time away from the real task of educating children.
