Now there's something you don't see every day, it appears a 20' northern bottle-nosed whale has gone on a site-seeing tour of central London, starting with river cruise up the Thames.
Cynical observers claim that the whale has 'lost its way', others think he's just taken the opportunity of a rare sunny day in London to cruise the river.
BBC online are offering a live video stream entitled "Watch the whale in the River Thames", featuring live real-time video of the whale in action. Or at least they would be if they hadn't lost it. Stay tuned!
