SINGAPORE • Singapore Prime Minister (PM) Lee Hsien Loong’s siblings have brought a smoldering family feud back into the public domain via Facebook, after the state counsel asked the Law Society to look into possible misconduct by the premier’s sister-in-law.

The Attorney General’s Chambers (AGC) has referred a case of possible professional misconduct involving Lee Suet Fern of Morgan Lewis Stamford LLC to the Law Society, it said in a statement yesterday. Hours before the AGC’s statement, its actions had been publicised by Lee Wei Ling, the current PM’s estranged sister, in a Facebook post on Sunday night.

Suet Fern, who is married to the PM’s younger brother Lee Hsien Yang, appears to have prepared the last will of former Premier Lee Kuan Yew even though her husband is a son of the late PM and a beneficiary, according to the AGC. That appears to breach conduct rules of the legal profession, it said.

Hsien Yang has said publicly that the will was drafted by Kwa Kim Lee of the law firm Lee & Lee, though the latter has denied drafting it, the AGC said.

The will became a source of contention amid a row over the fate of a colonial-era bungalow that belonged to Lee Kuan Yew. The late Lee lived there for much of his 91 years and his will included a wish for the property to be demolished eventually. All three children have said they want to honour that request, but the two younger siblings have accused PM Lee of manoeuvring behind the scenes to undermine their father’s instructions.
