From Lynne Jones MP.

Sir, Meg Hillier’s defence of the ID card scheme (Letters, November 29) omits crucial information. She mentions that the ID card database will hold core identity information and will not be an amalgam of all existing government data. This is true but the amount of information stored about us could grow exponentially without our necessarily knowing – the plan would be to track the occasions our identity is checked on the database, giving the government access to our movements.
