A former aide to Ko Wen-je has publicly mocked Ko's wife Chen Pei-chi, turning a family spat into a fresh embarrassment for Taiwan's TPP.

• Chen Pei-chi, a doctor and wife of jailed former TPP chairman Ko Wen-je, posted that President Lai Ching-te holds a grudge over lost votes and is steering the courts against her husband.
• She also claimed "disliking Lai Ching-te is the consensus of 60% of Taiwanese," which drew pushback online.
• Ko's former photographer Pan Chun-lin contrasted her with Chen Shui-bian's daughter Chen Hsing-yu, also a doctor, saying one quietly raised three children alone while the other blames the world.
• Chen Pei-chi says Ko has had no salary since retiring from his hospital job and now lives on nothing after his pension was seized.

Outlook: The sniping is likely to keep growing as Ko's legal case drags on and his allies split over how loudly to fight it.
