ST [Mr Loh was secretary of AHPETC from August 2011 till last month, and was also managing director of estate management company FM Solutions and Services (FMSS), the town council's outgoing managing agent.
The role saw him at the centre of a controversy earlier this year, when the Auditor-General's Office, in its report on AHPETC's accounts which was debated in Parliament, singled out governance lapses and conflicts of interest involving FMSS.
Mr Loh and Ms How, his wife of nearly 30 years, had been long-time WP supporters.
The couple cut their teeth in estate management at the former Hougang Town Council, working for WP chief Low Thia Khiang since the 1990s.
Mr Loh provided lift maintenance and rescue services.
The couple formed FMSS, where both are majority owners, shortly after WP won Aljunied GRC at the 2011 General Election.
Mr Loh was also the owner of FM Solutions and Integrated Services, a contractor AHPETC had hired to provide lift maintenance and rescue services.
However, the WP will run AHPETC on its own from this month, after a tender it held last November did not attract a single bid, even from FMSS.
