Last week we heard that DNA data from 4,000 serious crimes abroad were "lost" in the desk of someone on long term sick leave within the Crown Prosecution Service and meant they were not acted on for a year.

And low and behold, we hear that 11 of those wanted people were not only in the UK but had committed further crimes here.

Offences which could have been prevented if the CPS had done its job properly.

We're not talking about minor offences, it's murder, rape and other serious crime.

This loss of data follows on the heels of other disasters which include the loss of 25 million people's child benefit details, the theft of a Royal Navy laptop containing 600,000 people's details and those of three million British learner drivers, held on a computer hard drive, had gone missing in the US.

When vital details such as these go missing, the civil servant responsible and the bosses should be instantly sacked, together with the minister responsible – and not just the ministerial post but as an MP too, to give the electorate the chance to show its displeasure at a by-election.

This latest debacle also shows just how much flotsam from across Europe and elsewhere (and I am not talking about wood!) is ending up on our shores.

It also shows how important it is that we properly police our borders. Without question there are many, many people living in this country today who have no right to be here – ever.
