Ikea probes forced labour claims

3 May 2012 Last updated at 02:45 BST

Furniture retailer Ikea is investigating claims it used forced labour in former East Germany to make its furniture during the 1970s and 1980s.

An investigation by a Swedish current affairs programme unveiled secret police files from the East German Stasi.

The station claims to have found evidence East German prisoners were used for forced labour and some were political.

Former prison guard Joachim Kreyss said they took it for granted that they were criminal prisoners, as Theo Leggett reports.
