Like our beloved Majesty, I too am celebrating a platinum anniversary: I have been reading the Guardian for 70 years this month. I even had the airmailed Guardian Weekly when I lived in Singapore to keep up my unbroken record. At first it was mainly to have the crossword, and politics were more straightforward then. But the paper has risen to its challenges and I salute you for it.
