The Deputy Prime Minister's department has managed to display astonishing ignorance about a subject which is one of its direct Ministerial responsibilities:

Deputy Prime Minister
Fire Service (Mobile Communications)
Bob Spink (Castle Point, Con): To ask the Deputy Prime Minister how many instances have been recorded of the fire service using mobile phone location data to effect a rescue operation. 
Jim Fitzpatrick (Parliamentary Under-Secretary (London), Office of the Deputy Prime Minister) The information requested is not held centrally. The fire and rescue service is not responsible for tracking criminals.
N.B. this is a Written Answer, not an "off the cuff" oral one.
The Office of the Deputy Prime Minister is the Government department which sets the planning policies which affect the siting of Mobile Phone mast transmitters. The ODPM is also responsible for the planning applications for the TErrestrial Trunked RAdio (TETRA)
masts used for the Airwave encrypted radio service used by the Police, Ambulance, and Fire and Rescue services.
It is the physical locations of these masts, which are used by third party companies to offer Mobile Phone Location Based Services to consumers (which have their own potential privacy and security problems) and which can also be used to provide the approximate locations of 999 / 112 mobile phone calls to the Emergency services.
If the primary use of Location Based Services, so far as the ODPM is concerned, is for for the electronic tagging of criminals or the tracking of criminals via their mobile phones, what chance is there that they will not see the forthcoming eCall the pan-European in-vehicle emergency call system which is due to be fitted to all new vehicles in the European Union from 2009, as just another way of keeping the UK public under control ?
