 By 1848 when an evangelical John Bird Sumner became Archbishop of Canterbury, between a quarter and a third of all Anglican clergy were linked to the movement, which by then had diversified greatly in its goals and they were no longer considered an organized faction.In the 21st century there are an estimated 2 million Evangelicals in the UK.According to research performed by the Evangelical Alliance in 2013, 87% of UK evangelicals attend Sunday morning church services every week and 63% attend weekly or fortnightly small groups.
