From The Register:

Almost one in ten records within HMRC’s framework database contain errors, according to figures unveiled by Conservative MP Justine Greening.

The frameworks database only contains quite simple information - first, second and surname, title, sex, data of birth, address and National Insurance number. Which begs the question of how many errors more complicated government records contain. It costs £7.5m a year to maintain it.

Even more worrying of course is the government’s continued enthusiasm for more and more databases, and the ID card scheme, which makes such errors ever more damaging and difficult to correct.
