John Tsang
In the 2017 Chief Executive election, Tien supported his party chairwoman Regina Ip. He complained the election had "lost its shape" due to the increasing interference of "an invisible hand", referring to the Liaison Office. Tien inclined his support for John Tsang after Ip dropped out, although Ip endorsed Carrie Lam on the last day before the election. Tien eventually quit the party on 10 April with six District Councillors.
