Hong Kong democracy activist Tony Chung, who once called for the city¡¯s independence and was the youngest person to be jailed under its national security law, has been granted asylum in the U.K.

Chung, 24, posted a letter from the U.K. interior ministry on his Instagram page on Sunday, which read, ¡°Your claim for asylum has been successful and you have been granted refugee status.¡±

U.K. authorities accepted that Chung has a ¡°well-founded fear of persecution and therefore cannot return to your country.¡±
