The Dame, back from buying her weekly supply of anti ageing vitamins from Holland and Barrett, happened to walk past the Ecuadorian Embassy.
She was met by the extraordinary sight of eight police vans and twice as many officers loitering around looking bored stiff.
The Dame won't embarrass the officer but she got the distinct impression he felt much more strongly about it than she.
He even suggested, with a roll of his eyes, that it could go on for years.
It's time we said to the Swedes"if you want Assange back so badly you pay the policing costs".
Bernard Hogan-Howe and his hopeless boss, 'Not the Bottom Pincher' Greenhalgh, need to get down to Knightsbridge and judge themselves the lunacy of keeping so many officers tied up whilst Londoner's lives are threatened by murderous terrorists.
One officer is sufficient for the purpose of this pointless exercise.
