In this brand new Channel 4 series hosted by AJ Odudu, millionaires, collectors and dealers come face to face in a special built arena as they compete to buy the most extraordinary items with the most jaw dropping backstories. From a piece of wall with a Banksy, a piece of Will and Kate’s wedding cake to Saddam Hussein’s fork and a Louis Vuitton skateboard, there will be huge wins and bitter losses when the hammer falls on The Greatest Auction.
