Britain has revoked the visa of Shinawatra, who has been living there in exile since he was ousted in a coup in 2006, reported Timeturk.
Meanwhile, Thai newspapers reported on Saturday that Shinawatra has divorced his wife in Hong Kong.
Thaksin and his wife Pojaman Shinawatra, who married in 1976, divorced at the Thai Consul General Office in Hong Kong on Friday, the Nation and Bangkok Post reported.
The stories could not be independently verified with the consulate.
