A tainted-cooking-oil scandal has escalated into a Taiwanese political power play, and the two opposition parties are now feuding over how far to push it.

• KMT Taipei Mayor Chiang Wan-an wants a no-confidence vote to force Premier Cho Jung-tai out over the cancer-linked oil scandal.
• A report says a KMT lawmaker is quietly pitching a deal: run joint opposition candidates and hand the first 5 at-large seats to the smaller TPP, to reach the votes needed to topple the cabinet.
• The TPP blasted the offer as an anonymous stunt to "take advantage and test the waters," saying the KMT should first build its own internal agreement before approaching them.
• The ruling DPP mocked the plan too, arguing a no-confidence vote based on a backroom seat-swap is a corrupt power trade, not real accountability.
• Many KMT district lawmakers reportedly dislike Chiang's timing, fearing a fresh parliamentary election would hurt them in year-end local races and deepen political instability.

Outlook: Without a firm KMT-TPP agreement, the no-confidence push looks unlikely to advance soon, and the two parties will keep sparring over whether to aim at the cabinet or at President Lai directly.
