The driver of a truck in which 39 Vietnamese nationals were found dead has pleaded guilty to assisting unlawful immigration at a court in London.

Maurice Robinson, appearing on a video link from prison, also admitted to acquiring criminal property.

The 25-year-old, from Northern Ireland, did not enter a plea to 41 other charges, including 39 counts of manslaughter.

The victims were discovered at an industrial site in Essex last month inside a refrigeration container that had been shipped from Belgium the same day.
