John Lee, formerly the city's No. 2 official, revealed his 44-page manifesto Friday, vowing to strengthen governance, increase public housing supply, boost the city's competitiveness and build an inclusive society focused on upward mobility. Lee said he would “fulfill the constitutional responsibility of legislation” under Article 23 of Hong Kong's mini-constitution, the Basic Law, as part of improving governance. Article 23 stipulates that the city shall enact its laws to prohibit “any act of treason, secession, sedition, subversion against the Central People's Government," and “theft of state secrets.”
