Thought for the Day: why did none of the normally erudite panellists on Radio 4's Brain of Britain quiz know which European city had been awarded the riba's Gold Medal this year? (It was, of course, Barcelona). Getting a message across is tough. I hope the institute is making proper arrangements for the Stirling Prize being held in Glasgow, especially after last year's shambles. Why have no invitations been sent out, especially when the tickets for the bash, in Glasgow's Kelvingrove, are £100 a time?
