The Democratic Party yesterday renewed its threat to vote against the Budget if the Government failed to increase monthly social security payments for the elderly by $300.

Legislator Law Chi-kwong said his party had told Financial Secretary Donald Tsang Yam-kuen its views.

'To increase the payments by $300 a month would only add $360 million. This . . . accounts for only 1.5 per cent of total expenditure,' he said.
