Phew. Let's look at the figures they quote:
Figures from the Department for Children, Schools and Families showed that on average, 7.1 per cent of 11- to 15-year-olds were taught in independent schools in 2004. But by this year the proportion had risen to 7.3 per cent - a total of 232,620 pupils.
There was also a rise in the number of primary-school age children in private education over the three-year period, from 5.5 per cent to 5.6 per cent - a total of 199,030 pupils.
So there's been changes of 0.1 or 0.2 percent. Not quite an 'abandonment' then.
