Lizzie, I took the trouble to look up the numbers of pupils in single sex girls schools.

There are approximately 140,000 girls in single-sex state schools.

Now why didn't you do that before suggesting they didn't exist.

You might care to note - pupils especially girls tend to get better results in single sex schools - but parents tend to prefer mixed schools. That's why the numbers have dropped from 2,500 single sex schools to the current figure.

See Lizzie, despite all the evidence, parents know best.
