Record low proportion of Leeds weddings being held in religious venues

The UK's largest humanist group said a national decline reflected couples increasingly wanting a ceremony that matches with their non-religious beliefs.
That means just 23% of ceremonies were religious – the lowest rate since records began in 2001.
That is down from the highest rate, 41%, in 2001.
Humanists UK said they already perform more than 1,000 non-legally recognised humanist wedding ceremonies each year in England and Wales.
Chief executive Andrew Copson said: "The vast majority of people in England and Wales identify as non-religious and this is growing each year with no sign of changing so it's not surprising that couples don't look to religion to celebrate the most meaningful moments in their lives any more.
"Instead they want non-religious ceremonies that reflect their beliefs, their values, and their love."
Paul Butler, the Bishop of Durham, said a church wedding is a unique occasion where time-honoured vows are exchanged in a "special and spiritual atmosphere".
He said: "We know from research that many couples want this for their wedding day, whether they are regular churchgoers or not.
"I would like to reassure couples that they don’t have to be christened or confirmed, and we welcome couples who already have children – just ask."
The same ONS figures show 3.8% of weddings held in Leeds were between same-sex couples – 41 between men and 46 between women.
It means the area is above the average across England and Wales, where a record 2.9% of weddings involved same-sex couples in 2017.
Laura Russell, director of campaigns, policy and research at Stonewall, said: "While there’s still lots to do before the lived day-to-day experience of many lesbian, gay, bi and trans people is truly equal and many same-sex couples across the world aren’t able to marry, this news is a hopeful sign of more good things to come."
