THE Boundary and Election Commission has been asked to condemn the vandalism of candidates' publicity materials after another case was reported yesterday. The commission was also asked to increase protection for candidates because of death threats made to Democratic Party candidate Mak Hoi-wah on his posters. Mr Mak's canvassing team found yesterday that most of his posters and a van used for publicity had been covered in red paint. Mr Mak, a contestant for the Kowloon Northeast seat, said four Chinese characters could be read on his van, saying 'he must pay with his life'. 'Other phrases bearing similar meaning, such as 'pay for a life', have also been found on my posters in the Wong Tai Sin public housing estate and the other two nearby estates,' he said. 'Such action threatens my person and my family members' security. It is an attack on the democratic elections. 'The commission must do something to stop it as such activity will discourage people from voting,' he said. Mr Mak said there was no reason for the attack and he believed the move must be linked to the election because all his posters were destroyed but not those of his competitor, Chan Yuen-han. But Miss Chan, a pro-China Democratic Alliance for the Betterment of Hong Kong member, said her campaign had also been targeted in the past few weeks. 'The situation has never been improved,' she said. 'It is as bad as the last time when I ran for election in 1991. 'I feel sorry as it shows the election cannot be launched under a fair environment,' she said. A commission spokesman said 110 complaints of this sort had been received. He said it would investigate Mr Mak's case before deciding what action to take about the matter.
