You're absolutely right, and I apologise for not making the case for SEN children. State SEN provision is woeful and should be improved - and until it is (if it ever is) of course parents will seek out any way of providing for their children's needs. I think that if you have an SEN child you should be exempt for any VAT charged on their educational fees
I have a close relative with Down Syndrome, whose state education was woeful, which makes my failure to make the case even more unforgiveable
I wasn't suggesting, however, that I think private schools should be abolished. Firstly, I don't think it's possible to ban them and, secondly, I don't believe they should be banned.
