Hong Kong's No. 2 official, John Lee, said on Wednesday he had resigned to run in a leadership election in May, two days after Chief Executive Carrie Lam said she will not seek a second five-year term.
Lee said he was awaiting Beijing's approval for him to stand in the leadership election.
Lee, 64, a former deputy commissioner of police, was promoted to the global financial hub's No. 2 role in 2021 in a move that some political analysts said signalled Beijing's priorities for Hong Kong were related to security rather than the economy or finance.
