Объединённые демократы
In 1990, some leading figures of the ADPL such as vice-chairmen Lee Wing-tat and Albert Chan joined the United Democrats of Hong Kong, which later became the Democratic Party. The ADPL retained its separate identity, arguing that it represented grassroots interests whereas the United Democrats were more focused on the middle class. However, as many members joined the new party, the ADPL's membership dropped significantly to only 70 members, 15 District Board members and two municipal councillors.
