From The Guardian Live Blog:
3.04pm: The veteran journalist John Pilger was rejected as one of the sureties. The judge described him in court as “another peripatetic Australian” like Assange.
Vikram has been trying to get to the bottom of how many sureties are now required. He says they need to find five today in addition to the two individuals identified on Tuesday: Vaughan Smith and Sarah Saunders.
It is believed that one or two of the additional five are outside London. They all need to sign the paperwork before Assange can be freed.
