Muslims have the strongest faith in modern Britain while only one in six who identify with Anglicanism or other mainstream protestant churches are convinced of the existence of God. Women are almost two-thirds more likely than men to believe in God, a major study of attitudes among middle-aged Britons has found. Atheism and agnosticism are now the majority creed among the male population but almost two thirds of women believe in Heaven or an afterlife. The findings also suggest that Muslims have by far the strongest faith , with Christians from smaller evangelical churches the only group coming close to the same levels of certainty. By contrast only one in six members of the main Protestant denominations say they believe without doubt in God. Just a third of Roman Catholics in the study said the same compared to 88 per cent of Muslims and 71 per cent of those categorised as evangelical Christians.
