The DVLA has sacked 14 staff members for sending pornographic emails at their Swansea headquarters.

A further 101 staff were disciplined, some given final warnings.

A spokeswoman said the pornography had been downloaded from the internet by staff during working hours and then sent around the building. She said that tighter controls had been introduced which would monitor all emails with images attached.

A female worker who did not want to be named, quoted in The Times said: 'Work can be very tedious and people find ways of livening up their days.

'The early stuff was pretty innocent, a joke really. A very boring document would have a picture of a naked woman attached, for example.

'I suppose it was bound to get out of hand. The stuff became more outrageous and then some of the men started sending ordinary emails to female colleagues and then watching their reaction when they opened the attachment.'
