SINGAPORE - One more top official at Singapore Post is leaving with the resignation of its deputy chairman and executive director.

"Mr Goh Yeow Tin wishes to devote more time to his other commitments and shall resign from the Board," SingPost said in a filing to the Singapore Exchange on Wednesday (May 25), adding that he departs from the company with effect from June 24.

Mr Goh oversaw SingPost's post-merger integration activities and the business and operations in Singapore since Jan 1 this year, following the surprise resignation of former chief executive office Wolfgang Baier in December last year. Dr Baier was followed by chairman Lim Ho Kee, who departed on May 10 and will step down as a director after the company's annual general meeting in July, and lead independent director Keith Tay who resigned on May 12.

Last week, the Accounting and Corporate Regulatory Authority (ACRA) announced investigations into the company over possible breaches of the Companies Act, after a special audit report that identified lapses in disclosures relating to acquisitions by SingPost that involved Mr Keith Tay.

Besides sitting on SingPost's board of directors, Mr Goh also holds directorships in 10 other businesses, including Vicom and Sheng Siong Group.
