A memorial to the 200 Britons who were executed by the Nazis at Natzweiler-Struthof, near Strasbourg - the only World War II concentration camp in France - is to be unveiled next month.

Among those killed there was 29-year-old WAAF, Diana Rowden, of Alton, who had been working as a secret agent in France when she and three companions were betrayed, taken to Natzweiler-Struthof, and killed in July, 1944.

The murders are recorded on a memorial plaque at the crematorium there and the French government posthumously awarded Diana the Croix de Guerre.

Hampshire MEP, Roy Perry, will be one of the guests at the laying of a foundation stone for a memorial centre on the site of the camp over the weekend, June 21st-22nd.

"At a time when Anglo-French relations are not at their best, it is worth us all remembering the great support given by Britain to France in its blackest hour and also the very genuine feeling that French people have for such people as Diana Rowden, who gave her life so that France could be free," he said.

"This was brought home to me in the European Parliament, in Strasbourg, when a French MEP said he felt shamed by the recent desecration of the war memorial at Etaples, and that he wished to apologise to all British people for a such a mindless act by French hooligans.

"We have the shared hope that the memorial at Natzweiler-Struthof will be a poignant and fitting monument," he said.
