A mother-of-two and her alleged lover, a fellow Briton, were sentenced to two months in jail in Dubai after being convicted of adultery, the British embassy said.
"I can confirm that they have been sentenced to two months in jail, followed by deportation,'' embassy spokesman Simon Goldsmith said.
Sally Antia, 44, married for 14 years and who has reportedly lived in Dubai with her husband for 13 years, was caught leaving a Dubai five-star hotel with Mark Hawkins, 43, on May 2.
Her estranged British husband had tipped off police in the relatively liberal Muslim emirate, which still criminalizes sex outside wedlock regardless of the religion or nationality of the people involved.
The man went to the police after Antia spent six days with Hawkins, who was visiting Dubai, the local daily 7Days said.
Antia had pleaded guilty in her first appearance in court, but Hawkins denied the charges.
"They had been friends for four years ... My client is a father of four children and he is a visitor and doesn't know anything about our law and regulations. I want mercy for him,'' Hawkins lawyer Aiman Mirdas told the judge on Tuesday, according to the daily's online edition.
Antia's husband is reportedly seeking divorce while they are locked in a custody battle over their two daughters.
The verdict comes a month after another British mother-of-two jailed for adultery was released before the end of her three-month imprisonment, following a campaign by supporters and Amnesty International.
