Arch-enemies from the pro-democracy and pro-government camps will face off over six seats in what is arguably the most symbolic battle of the Legco election - the Hong Kong Island constituency.
The political contrasts could not be sharper. Candidates in the September 12 polls include Yeung Sum, leader of the Democratic Party, and his chief political adversary, Ma Lik, chairman of the Democratic Alliance for Betterment of Hong Kong (DAB). The popularly dubbed 'goddess of democracy', Audrey Eu Yuet-mee, is in the contest, as well as pro-government heavyweight Rita Fan Hsu Lai-tai.
The fact that so many political stars will collide in the traditional pro-democracy stronghold makes it the most symbolic battle in the elections, says political scientist Li Pang-kwong of Lingnan University.
'This is the key battleground between the pro-democracy and pro-Beijing camps, as both leaders of the Democrats and the DAB and their allies will meet head-on in Hong Kong Island,' he said. 'This is the ultimate showdown.'
Democrats dominated the constituency in 2000, denying the DAB all but one of the five seats available then, and hope for a repeat.
Initially the pro-democracy camp thought the best approach was to field a single list of big names. But after lengthy and sometimes stormy negotiations, it decided to run four candidates on two separate lists - Dr Yeung and Democratic Party veteran Martin Lee Chu-ming on one; and Ms Eu and Cyd Ho Sau-lan on the other.
The number of voters in the electorate has declined from 627,148 in 2000 to 618,451, so Democrats hope for a high turnout and careful co-ordination of votes.
