Candelight vigil . . . pro-democracy activists gather for a National Day vigil near the Tsim Sha Tsui clock tower last night. At a reception to mark the day, a senior Chinese official denied increased reports of corruption in the Hong Kong police force were linked to the handover. 'Corruption happens in Britain. What is it related to? It happens in the United States - again what is it linked to?' Xinhua Deputy Director Zhang Junsheng said. 'Britain, the US, Japan and the mainland have graft in their countries. Are they all something to do with 1997?' His comments came after the Independent Commission Against Corruption released figures showing a surge this year in police-related graft cases.
