This was the beginning of a national scandal which involved journalists, web users and MPs.
The Guardian has this article online which explains how the story, which Trafigura never wanted to be told, was broke.

Twitter was incredibly busy with thousands of people posting tags such as “Minton report”, “Trafigura” and “Carter-Ruck”. Within the space of a few hours more and more people were finding out what had happened.
In part due to web users, other newspapers and more MPs becoming informed, the super-injunction was lifted on 16 October, 2009 after Carter-Ruck announced that the Guardian should “treat these orders as discharged”. Carter-Ruck’s attempt at gagging the Guardian on reporting parliamentary proceedings had failed.
