A rift in the first family of late gaming tycoon Stanley Ho Hung-sun deepened on Tuesday after his eldest surviving child distanced herself from her sister following legal action by the latter to register interest in their father’s estate in Hong Kong.

In a statement issued through her lawyers, Angela Ho Chiu-yin said she and the rest of the first family did not support the caveat filed on June 5 by younger sister Deborah Ho, which she described as “completely irresponsible and inappropriate”.
