US/UK spying at the UN

Over in London, the Observer has just run a story providing details of US and UK spying at the UN and how it was used to derail an attempt to delay military action against Iraq.
Now in the UK, the relevant ministers are certain to be asked whether they approved the spy operation (in which case their explanations/excuses will be eagerly awaited) or not (in which case the question is simply “who’s in charge?”). Either way, it’s more bad news for Blair.
But will any US media pick it up? Will Bush or Rumsfeld or Powell be asked to explain why America conducts covert operations against the representatives of sovereign nations at the UN? If not, why not?
The story is here.
