French President Nicolas Sarkozy says British Bishop Richard Williamson's views that the Holocaust did not take place are "shocking."

"It is incredible, shocking and inadmissible to be able to find in the 21st century somebody who dares question the gas chambers, the Holocaust, the martyrdom of Jews. It is inadmissible," Sarkozy said on French television Thursday night.

However, Sarkozy refrained from any comment on Pope Benedict XVI's decision last month to lift the excommunication of Williamson and three other ultraconservative bishops. They were excommunicated in 1988 after they were consecrated without papal consent by the late ultraconservative French Archbishop Marcel Lefebvre.

Williamson was shown on Swedish state television several days before the lifting of his excommunication, expressing his view that no Jews were killed in gas chambers during World War II.
