A survey by Christian Research has found that, while 42 per cent of women longed to be Mary when they were at school and 23 per cent of men had coveted Joseph's role, as adults the most popular role is King Herod, who ordered the death of all young boys in Bethlehem.
In its survey last Christmas, Christian Research found that 79 per cent of Britons want to see nativity plays in their schools, with those in the eastern region most likely to want them and those in London the least.
