The new housing chief says his job is to keep the property market stable, but not to tell people when is a good time to buy. And Secretary for Housing, Planning and Lands Michael Suen Ming-yeung was keen to stress yesterday that he alone could not control the market. Mr Suen surrendered the constitutional affairs portfolio to become secretary for housing, planning and lands under the ministerial system. Speaking at a media briefing yesterday, he said it was government policy to keep the property market stable. Earlier, in a Commercial Radio programme, Mr Suen reiterated the administration's determination to keep out of the market. Asked if he would advise people on when to buy, he said: 'You won't get that from my mouth.' Former secretary for housing Dominic Wong Shing-wah had been criticised for calling on people to buy property, claiming the market had become stable. Mr Suen said yesterday he was ready to step down if he was found to have an integrity problem. He declined to comment on other scenarios such as policy blunders and failures. The ex-director of housing, Tony Miller, and former Housing Authority chairwoman Rosanna Wong Yick-ming, were pressed to stand down in the wake of the short-pilings scandal on public housing construction sites. Ms Wong resigned before a Legco vote of no-confidence. Mr Miller stayed on and has assumed a new role as permanent secretary for financial services. On Commercial Radio, Mr Suen said the current waiting time of three years for public housing applicants could be shortened if the number of mainland migrants arriving in Hong Kong for family reunion was reduced. Around 85,000 families are in the queue for public housing.
