Pope Benedict XVI has been criticised for lifting the excommunications of four men ordained without papal permission.

Briton Richard Williamson, told Swedish television in November 2008 that he did not believe any Jews had died in gas chambers during the Second World War.

Mr Williamson, a member of ultra-traditionalist sect Society of St. Pius X was automatically excommunicated 20 years ago after being appointed as a bishop by a breakaway archbishop without papal consent.
