The demonstration took place near the site of the Beijing Olympics
A British woman is returning to the UK from China after being held in jail there for three days without charge after a Free Tibet demonstration.
Mandy McKeown, 41, from Bristol, had been expected to be detained for 10 days following the protest in Beijing.
But British Prime Minister Gordon Brown raised her case when he met Chinese counterpart Wen Jiabao on Friday.
She was deported hours after the Olympic Games closing ceremony and is due to land at Heathrow Airport later.
Arrested for filming
Ms McKeown will be welcomed at the airport by friends, family and members of London's Tibetan community.
No 10 said China's Ministry of Foreign Affairs had taken notice of the "personal interest" of Mr Brown.
Mother-of-two Mrs McKeown was arrested while filming the protest near the site of the Beijing Olympics on Thursday.
Two Americans and a German were also detained by the Chinese authorities.
Mrs McKeown has a five-year-old son and a three-year-old daughter.
