And the decline in Christianity has fallen from 40.2million down to 36.1m with further declines projected. Christianity is still the largest faith group in the UK by a significant margin but those falling away from the church are increasing in numbers and more has to be done by faith leaders to prevent further decline, says the report. The Casey Review published earlier this month shows that Islam is now the largest non-Christian religious population in the UK.

Faith leadership has not to date been strong enough to counter the vocal minority who are bringing religion into disrepute The Casey Review

Meanwhile a separate report published by the Brierley Consultancy says UK Church membership has declined from 10.6m in 1930 to 5.5m in 2010. The first mosque in Britain, called the The Shah Jahan Mosque, was built in Woking, England in 1889 and there are now an estimated 1,750 in the UK. Meanwhile Christianity in Britain is largely associated with the mission of Augustine in 597 AD however it is thought to have arrived as far back as the 1st Century AD. The Casey Review report states: "Faith leadership has not to date been strong enough to counter the vocal minority who are bringing religion into disrepute and influencing the attitudes of people who increasingly regard religion as a force for bad. "But there has been a significant shift in the religious landscape of the nation, with a reducing number identifying themselves as Christian, more people saying they hold no religion and more diverse and growing minority faith populations, of which Muslims are the most prominent.

"This increase in the diversity of faiths and beliefs in the UK has increased the visibility of tensions between religious groups and the presence of more visible signs of religion, for example in the growth of mosques, and led to increased anxiety – which has not been sufficiently acknowledged or discussed. "We remain predominantly religious, with nearly seven out of 10 of us belonging to a religion. "Christians remain a majority, while a quarter of the population holds no religion. But the proportion of Christians fell from 70 per cent to 59 per cent, while the proportion holding no religion grew from 17 per cent to 26 per cent. "The number of people belonging to the other main religions grew, with the exception of the Jewish population which remained around the same size.

"Among faith groups the number of people identifying themselves as Muslim grew most significantly, by 1.2m people. "This 72 per cent increase is higher than for any other religious group and Muslims make up the largest non-Christian religious population in the UK at 2.8m in total, compared with 0.8m Hindus, 0.4m Sikhs, 0.3m Jews and 0.3m Buddhists." While the Brierley Consultancy report says: "The UK Church membership has declined from 10.6m in 1930 to 5.5m in 2010, or as a percentage of the population; from about 30 per cent to 11.2 per cent. "By 2013, this had declined further to 5.4mn (10.3 per cent). If current trends continue, membership will fall to 8.4 per cent of the population by 2025. "In England, membership is forecast to decline to 2.53m (4.3 per cent of the population) by 2025."
