British couple who 'performed sex act' in wedding photo at Greek monastery face being SUED after church cancelled all foreign weddings there... as even groom's grandfather says: 'I'm disgusted!'

A Greek bishop has reportedly banned all foreign couples from marrying at a sacred site after a couple posed for a controversial photo at a monastery.

British couple Matthew and Carly Lunn's daring wedding photo appeared to show the bride carrying out a sex act on her new husband.

The picture showed Matthew, 27, punching the air in front of a picturesque lake as the sun set, with his trousers around his ankles and boxers pulled to his knees.

Carly, 34, is on her knees in front of him, her hands on his hips and her head in a very suggestive position.

The picture was posted on Facebook moments after they tied the knot in Greece - and their friends branded them 'legends'.

But Greek church chiefs were far from impressed.

But his grandfather has failed to the see the funny side, telling : 'I'm disgusted.' 

Angry Bishop Kyrillos has banned all foreign couples from marrying at the Greek Orthodox monastery of St Paul on Rhodes, believing the stunt was offensive to the holy setting, The Sun reports.

Matthew, a car breakdown firm worker, said: “It’s been blown out of proportion, we were just pretending and having a laugh.

"The Greeks have completely over-reacted.

“We don’t think we did anything wrong but we regret it and wish we hadn’t bothered."

He said the ban has caused them a lot of hassle.

Even Giorgos Eleftheriou, who married them, agreed with the bishop's ban, according to reports.

He's apparently had calls from hundreds of bride-to-be's in tears.

But he's reportedly said they can't allow such 'disgusting behaviour' at a religious site.

Carly, 34, earlier told Mirror Online she was stunned by the reaction it has received.

She said: "It was something we said we'd do for a joke, we agreed to do it before we got married and followed through with it.

"Everyone's loved it, it was a brilliant wedding photo."

The image was taken by a family member of Matthew's after their wedding on September 25.

After the picture went online, the couple were soon receiving messages from friends and family in the UK and Greece.

"It was just a photo, we did it away from the guests and it was a bit of fun," Carly said.

"We expected a lot of laughs and jokes from people, but didn't expect it to be as popular as it was. People back in England were commenting on it, the whole thing went mad."
