Two Britons convicted of kissing in public had their one-month prison sentence upheld by a Dubai court today.

Ayman Najafi, 24, and 25-year-old Charlotte Adams were arrested by police in the Gulf resort last November after a woman complained they had been seen kissing on the mouth in a restaurant, breaching Dubai's strict decency laws.

They were sentenced last month when a judge at Dubai's Misdemeanours Court heard written evidence from a 38-year-old mother who complained to police.

She said she was offended by their behaviour at the Jumeirah Beach Residence, where she was dining with her daughter.

The judge dismissed Mr Najafi's claim he had merely kissed Miss Adams on the cheek and sentenced both to a month in jail followed by deportation.

But the pair were bailed pending today's appeal which has now been rejected.

Mr Najafi has been working for marketing firm Hay Group in Dubai for about 18 months.

In 2008, two Britons accused of having sex on a beach got three months in jail, though their sentences were later suspended.
