Passport Photos
The Home Office claim that their automated systems can recognise a 4 year old from photographs of that 4 year old with their mouth closed and eyes open when they were 2 weeks old.
I accept the argument that babies should have passports (although we coped for centuries with children travelling on their parents' passports). However, I cannot believe that it is necessary to be as picky about the photograph of the child.
In the mean time over 13% of passport applications are rejected because of the photo not satisfying the government's new conditions.
