LETTER

London SE11

l NEVER mind the Union Jack which flies so obviously, and perpetually, from the Thames side of the new MI6 building at Vaxuhall (Captain Moonlight, 9 April). Even more interesting to the casual stroller across Vauxhall Bridge are the large number of operatives who can be seen enjoying themselves on the building's terraces on a sunny afternoon. No doubt they are engaged in working out how the tidal patterns of the Thames caused the demise of Stalinism.
