Swedish prosecutor's office says it has 'not got a view at all on bail' and that Britain made decision to oppose it

The decision to have Julian Assange sent to a London jail and kept there was taken by the British authorities and not by prosecutors in Sweden, as previously thought, the Guardian has learned.

The Crown Prosecution Service will go to the high court tomorrow to seek the reversal of a decision to free the WikiLeaks founder on bail, made yesterday by a judge at City of Westminster magistrates court.

It had been widely thought Sweden had made the decision to oppose bail, with the CPS acting merely as its representative. But today the Swedish prosecutor's office told the Guardian it had "not got a view at all on bail" and that Britain had made the decision to oppose bail.
