The old-fashioned attitudes and hierarchies of churches are causing a steep decline in the number of female worshippers, according to an academic study.

The report claims more than 50,000 women a year have deserted their congregations over the past two decades because they feel the church is not relevant to their lives.

It says that instead young women are becoming attracted to the pagan religion Wicca, where females play a central role, which has grown in popularity after being featured positively in films, TV shows and books.
