Major political parties are joining forces to limit rent increases in public housing estates at the last sitting of the Legislative Council. Legislators from the Democratic Party and Association for Democracy and People's Livelihood (ADPL) as well as some colleagues fighting for grassroots interests are to make a joint amendment to a bill moved by unionist Leung Yiu-chung. The amendment seeks to limit further the Government's discretionary power to raise public housing rent. Mr Leung's bill says rent increases should not exceed inflation. The new amendment says rent increase should be two percentage points lower than inflation and that the actual amount should not exceed 10 per cent of average income. Lee Wing-tat, Democratic Party housing spokesman, said the amendment would guarantee tenants could afford the increase by maintaining an upper ceiling. The Housing Authority's proposal to increase rents in order to meet its costs, he said, would burden tenants. 'It is very clear why the Housing Authority is suffering from a great deficit. It is because of its poor management. 'Tenants should not pay for the Government's mistakes,' said Mr Lee, a member of the Housing Authority. He said the new amendments would offer better protection to tenants. Bruce Liu Sing-lee of the ADPL and Mr Leung of The Frontier support the amendments, but the Democratic Alliance for the Betterment of Hong Kong and Federation of Trade Unions (FTU) have not decided on their position. Chan Yuen-han of FTU said the proposal for a limit on rent increases below inflation rate was not ideal. 'We can't always expect inflation in single figures. What happens if the inflation rate rises to more than 20 per cent?' she said. Mr Lee said he hoped that both the FTU and the DAB would abstain, so the Democratic Party could secure enough votes to pass the amendments.
