Ken Rigby, Midland's general manager in the North, wasn't saying how much it cost. 'It's not that I'm embarrassed about it. It's just that it's none of your business. Let's just say that it was cheaper than hiring the Dorchester.' Just for the record, the Dorchester Hotel in London says that a basic no-frills dinner in one of its smaller rooms for 150 people would cost about pounds 8,000. The catering department at Castle Howard says a dinner with all the trimmings would be about pounds 110 a head - pounds 16,500 for 150 people.
