How cities and countries get ready for big events like the World Cup and the Olympics, what challenges they face, and what opportunities these mega-events can create.
So far only three parties are known to have expressed an interest but a "handful" of others are expected in the next fortnight.
They have until September 30 to submit their bids to the Olympic Park Legacy Company (OPLC).
The OPLC is the body which is tasked with finding a tenant for the 80,000-seater venue in Stratford, east London.
The problem is that the last Government promised to hand over ownership of the Olympic Park to the OPLC, debt-free, so that it could do the financial deals to sell or rent out the venues to the private sector after 2012.
It's a pretty fundamental action to take. Would you be able to sell your house if you didn't have ownership of it or possess the deeds? No chance.
But the new coalition Government has now put that decision on ice, while the Treasury reviews financial decisions taken by Labour.
