Union rules

If David Cameron is looking for potential enemies, he need not worry about the Labour party. Mired in a five-way leadership race without any decent candidates or agendas, they are a danger only to themselves. Nor should he worry about rogue Liberal Democrats resigning to destabilise the coalition. His generous offer to hold a referendum on voting reform during next year’s May elections will keep them loyal until that date. The people with the energy and dedication to inflict damage on the government can be found in the teachers’ unions.

It is hard to overstate the power of teachers’ unions in Britain. For decades they have worked with local authorities to assert complete bureaucratic control over the schools system. The Education Secretary’s job is to pretend to have power (as Michael Gove will be finding out). The minister is tied like Gulliver in a matrix of regulations, legal threats, and arm’s-length agencies over which he has no power while the system is run by officials he can’t sack.
