Who forged the Niger documents?

Suburban Guerilla catches an interesting angle in a Guardian article:

Leaking the identity of an undercover agent is a serious crime under US law, but prosecutors would have to prove that the leaker was aware of the agent’s covert status. However, the investigation, led by federal prosecutor Patrick Fitzgerald, is reported also to be investigating possible charges of perjury and obstruction of justice.

Meanwhile, a parallel investigation is under way into who forged the Niger documents. They are known to have been passed to an Italian journalist by a former Italian defence intelligence officer, Rocco Martino, in October 2002, but their origins have remained a mystery. Mr Martino has insisted to the Italian press that he was “a tool used by someone for games much bigger than me”, but has not specified who that might be.

A source familiar with the inquiry said investigators were examining whether former US intelligence agents may have been involved in possible collaboration with Iraqi exiles determined to prove that Saddam Hussein had a nuclear programme.

Hmmm. Is there a parallel investigation or is Fitzgerald just expanding the original investigation??

In other news, the poor guy shot in the Stockwell Tube station yesterday turned out to be a Brazilian with no connection whatsoever to the London bombings.
