We've spent £9 billion paying for the London 2012 Olympics. The organisers say London 2012 will be an accessible and affordable Games, leaving a lasting sporting legacy. But 1.8 million British people applied for tickets in the public ballot - over a million applied for the 100 metres final alone - and the vast majority were disappointed.

So who got the tickets and for what events? Antony Barnett investigates in this Dispatches Special.

Fans queuing for hours to buy tickets get turned away empty handed while tickets for the same 'sold out' events appear online shortly afterwards, sometimes at astronomical prices. Channel 4 News correspondent Morland Sander investigates the multi-million-pound world of online ticket reselling where fans desperate not to miss out on in-demand concerts, festivals and sporting events often buy their tickets. Leading 'fan-to-fan' ticket exchange websites say they allow 'real fans' to sell on tickets they can no longer use. Dispatches sent reporters undercover inside two major 'fan-to-fan' ticket exchange websites to investigate who is selling via their websites and why so many tickets appear at over the face value so soon after the box office sells out.
