Martin Lee's Democratic Party chairmanship was also embattled with the intra-party factional struggles, in which he failed to resolve the ideological differences between the party members. The radical "Young Turks" faction launched a coup d'état in the 2000 leadership election by challenging the vice-chairman post held by Anthony Cheung from the moderate faction and eventually ousted Cheung from the vice-chairman post. The factional struggles intensified the "Young Turk" leader Andrew To proposed to put the minimum wage legislation on the 2000 Legislative Council election platform which caused a fierce debate within in the party and resulted in great disunity that led to the exodus of the "Young Turks" from the party and created a bad image in front of the public. Martin Lee's decision to support former Bar Association chairman and barrister Audrey Eu over his Democratic Party member in the 2000 Hong Kong Island by-election also received criticism within the party. In 2002, Martin Lee decided to step down as party chairman and was succeeded by Yeung Sum.
