UK's LTE Spectrum Auction Strategy

The UK is releasing auctioning off spectrum for 4G LTE services to be offered there. Journalists want to know how the auction is progressing. But the story by David Gilbert of IBT indicates that the UK's Ofcom knows how to run an auction:

Ofcom has said that no information about how the process is going until it ends. "Due to the nature of the auction, it is important that information about the bids being placed remains confidential until the auction concludes to reduce any potential risk of strategic bidding which could distort the outcome of the auction."
