Christian tradition should not be rejected in the drive towards a multicultural Europe, Cardinal Keith O'Brien has said ahead of a key European Court ruling on crucifixes.

Speaking a week before an expected decision by the European Court of Human Rights relating to the display of religious symbols in public the president of the Bishops' Conference of Scotland also warned that religious freedom was under threat.

"Europe is a multicultural and pluralistic continent where church and state are clearly separated and the rights of believers and non-believers are respected," he said.
