I am heading across the courtyard of Buckingham Palace for the third time in as many weeks. I am lugging a huge silver Sweaty Betty bag bursting at the seams with shoes and jackets. It is so large and so bling that it looks as though I’m trying to move in. And I realise, as the armed police officers wave me across to the diagonal corner — “look for the glint of red carpet” — past the sentry guards and the formal front gates, that once I leave I am unlikely ever to be invited back.
