More than 100 independent schools have clubbed together to host a stall at the show (stand number 1806A, since you ask). It's a natural link, apparently - the Independent Schools Information Service says: "For many parents, thinking about a home goes along with thinking about schools."
Hmmm. The Diary has never thought of public schools as ideal homes. Unless you're a parent whose ideal home is one without children, in which case boarding schools are pretty useful.
