Miss UK has spent a night in what is described as one of the most haunted places in the world to raise cash for a homeless project in Edinburgh.

Nicola Jolly, 23, was one of 10 people bedding down in vaults underneath the city's Old Town with just a sleeping bag for protection.
Streetwork UK hopes to raise enough to buy 300 sleeping bags, hats and pairs of gloves for those sleeping rough.
The volunteers spent Saturday night - All Hallows Eve - in The Caves.
They included Streetwork director Tam Hendry, who said: "We have to remember that many people sleep in dark and damp conditions like this every night, through no choice of their own.

"If the event is able to draw attention to the charity and the crucial front-line work we do on the streets of Edinburgh, then being scared to death for the night will be worth it."
Streetwork is a charity working with those at risk on the streets of Edinburgh.
Its team is out every day and night of the year, reaching more than 1,000 young people and 700 older people annually.
Those sleeping over at The Caves in Niddry Street South on Saturday night also included comedian and writer Kate Copstick.
