Mike Thomson investigates the role of the BBC Hungarian Service in World War II.

In March 1944 German troops occupied Hungary. In doing so they brought the Final Solution to the largest remaining Jewish population in Europe. Within months over 400,000 people were deported and killed by a now almost perfect mass killing machine.

Mike Thomson investigates documents which suggest that the BBC was directed not to broadcast crucial information and examines claims that it could have saved thousands of lives.
