Here is an illegal photograph.  I was on  a guided walk yesterday looking at new buildings near South Bank.  This is Palestra Building, home to Design for London, Transport for London and London Energy advice service, all not very secretive organisations funded by the tax payer when we were accosted by a security guard who told us that we could not congregate or take photographs.  All very mysterious, I had not intended to take any pictures but now felt compelled to do so.
