Six people linked to the pro-independence group "Returning Valiant", including minors, on Saturday admitted to conspiracy to incite others to subvert state power.

The six, aged between 16 and 26, admitted to committing the offence between January 10 and May 6 last year. They made their pleas at the District Court before a designated national security judge, Kwok Wai-kin.

The judge also granted a request by the seventh defendant in the case, Choi Wing-kit, who asked to enter his plea at a later time, once he had reviewed the revised case summary.

The court heard that the seven had distributed leaflets at street booths and made remarks advocating armed rebellion as the only way to change the government.
