The Nazi hunter, Simon Wiesenthal, and the German writer, Günther Grass, are making a public appeal to the Czech government to remove a pig farm from the site of a former concentration camp where about three-hundred gypsies died during the Second World War.

Campaigners for the gypsy community say the pig farm at Lety in the south of the Czech Republic is indicative of Czech attitudes towards gypsies.

But the BBC correspondent in Prague says many Czechs are opposed to moving the farm and argue that the money would be better spent providing practical help for gypsies.

Our correspondent says the issue is made more sensitive by the fact that the camp was set up and run by the Czech authorities loyal to Nazi Germany.
