Records of Jewish people who were deported from France during the Holocaust are to be revealed following a landmark decision by California legislators.
The French state train company SNCF is expected to place a bid to construct a high-speed railway between San Francisco and Los Angeles.
But last week, in a bill sponsored by Jewish lawmaker Bob Blumenfield, the California state legislature ruled that all companies bidding for the project had to disclose whether they had a direct role in Holocaust transportation between 1942 and 1944.
The project is worth an estimated £30 billion. SNCF has said the company had "nothing to hide" and that it would co-operate.
