Instant marriage for TV strangers
Six singletons are going to be introduced at the altar and immediately married off on TV in an attempt to find the formula for the perfect relationship.
The couples will take part in an experiment to find out if science can produce a stable marriage.
The Channel 4 show, which has a working title of Married At First Sight, is based on a hit Danish show and will see a pool of 200 people reduced to six singles willing to say "I do" without having met.
The couples will be matched up by a panel of experts and cameras will follow their first six weeks together. At the end of filming, they will be asked if they want to stay together or go their separate ways.
The broadcaster's chief creative officer Jay Hunt said the show was "a celebration of marriage".
She said: "It says marriage is important because of social cohesion. We don't have a great track record in that area.
"What if we take a slightly different approach and at its heart is the idea that we make the biggest decision of our life based on gut instinct and what if you got an array of experts to help inform that decision and you would be more likely to make the right choice?
"And what's interesting about it is in the countries where it's already played out, the feedback has been very positive and celebratory and the people involved in it have come back with a very different perspective on what they need from a relationship."
The channel is also planning documentaries looking at the treatment of dementia and newly-elected police commissioners.
Ms Hunt said she wanted to build on successful shows including Benefits Street and the coverage of the Winter Paralympics.
She said: "We're taking on Britain's reputation as the divorce capital of Europe in Married At First Sight and in Dementiaville we are exploring innovative research on the treatment of dementia."
