Satellite images found on the internet raise new questions about the level of Britain's involvement in the CIA's programme of extraordinary rendition.

The photographs of RAF Northolt in North-west London - freely available on sites including Google Earth - appear to show aircraft thought to be used to move terror suspects to secret interrogation sites.

The images of Northolt's Special Projects Area were found by Secret Bases, an organisation that highlights 'hidden' military sites, and were recorded between 2005 and early 2006. Up to two Gulfstream jets and four Cessna Citations can be seen in each shot.

Both types of aircraft are believed to be used by the CIA. There are also shuttle coaches and, even more sinister, an ambulance.

Secret Bases said: "Is this perhaps because rendition 'passengers' are routinely drugged in transit?"

The Government has already been forced to admit that two aircraft chartered by the CIA landed 14 times at RAF Northolt and RAF Brize Norton in Oxfordshire in 2003 and 2004.
