The horrific death by suffocation of 54 Burmese migrants when the ventilation failed in an airtight containter taking them to the tourist resort of Phuket is briefly in the headlines.

As a tourist, you have doubtless seen others like them against the backdrop of your fairy-tale holiday. It is a sharp reminder of the grim reality that lies behind seemingly normal and desirable "border controls".

Lest we forget, a similar tragedy killed 58 Chinese people in a container lorry in Dover a few years back. And Mexicans often suffer the same fate trying to reach their US destination.

We should not forget. Nor can we wash our hands of these deaths. They are caused by our callous but ineffective border controls.

Isn't it time we thought again?
