A Swiss court has handed jail sentences to four members of Britain’s richest family for exploiting Indian staff at their Geneva mansion.

The Hindujas, who were not present in court, were acquitted of human trafficking but convicted of other charges on Friday in a stunning verdict for the family, whose fortune is estimated at £37bn.

Prakash Hinduja and his wife, Kamal, were each sentenced to four years and six months in prison, and their son Ajay and his wife, Namrata, received four-year terms.
