LEGISLATORS have recommended to the Government that they be given wider scope for spending their $73,000 monthly allowances. According to government guidelines, the allowances may only be used for office expenses. But the Legco ad hoc group on the review of allowances, headed by veteran legislator Andrew Wong Wang-fat, said the rules should not be ''unrealistically restrictive''. It suggested allowing the money to be used for such activities as legislators' forums with constituents. Some legislators suggested a ''sanitisation period'' of six months before an election, to prevent allowances being used for campaigning. But the proposal was turned down, because the group did not think it ought to stop members performing their duties as councillors during their term of office. The Legco House Committee will today discuss the proposals suggested by the group.
