JANE FRYER: As the sky darkens and the rain sets in, the small crowd huddles against the concrete wall in anoraks, red woolly hats and Union Jack flags. They're queuing on the south side of Lambeth Bridge to file past the Queen's coffin, open for viewings from 5pm today and anticipated to attract 330,000 visitors at a rate of 3,000 an hour. And this lot really don't want to miss it.
