Thailand's ousted PM Thaksin Shinawatra has been ordered to appear before police in Bangkok next week to face corruption charges.
Mr Thaksin was ousted in a bloodless coup in September 2006
Thai police have charged Mr Thaksin and his wife with secretly concealing assets in a property company owned by his family.
Police said Mr Thaksin could face arrest if he did not show up.
He is currently living abroad, after his government was toppled in a military coup last September.
Mr Thaksin and his wife Pojaman were ordered to appear before the police by 29 June, police said.
"If they fail to appear, they could be sent to jail," Sunai Manomai-udom of the special investigations department said.
He said Mr Thaksin and his wife would be charged on two counts of violating disclosure rules concerning the company SC Assets, which was part of the family's Shin Corp telecoms empire.
Since he was ousted in last year's bloodless coup, a special committee has been investigating Mr Thaksin's affairs for alleged corruption.
The controversy surrounds his family's sale of Shin Corp to a Singaporean firm in January 2006.
In May, his party, Thai Rak Thai, was found guilty of electoral violations by a Thai tribunal, and ordered to be dissolved.
Mr Thaksin and more than 100 other senior party officials were banned from politics for five years.
Since he was toppled, the former prime minister has been living abroad - mainly in London. His wife has been in and out of Thailand.
