A public blowup inside Taiwan's opposition is bad news for the KMT and a gift to the ruling DPP, as party infighting overshadows a budget fight with the executive branch.

• Legislature Speaker Han Kuo-yu lost his temper and told KMT caucus whip Fu Kun-chi to resign after Fu skipped budget negotiations for the fifth time, calling the situation a sign of "dark forces" controlling parliament.
• Veteran commentators are turning on Han, saying that if Fu should quit, Han should also resign as Speaker for rushing to pass the central budget while the executive branch ignores laws the legislature already passed.
• Critics argue the Executive Yuan acted unconstitutionally first by refusing to sign and enforce six passed laws, so the opposition has no reason to hurry and bail out the government's budget.
• Some say Fu's absence was a "soft protest" backed by the caucus, and that Han demanding his resignation oversteps a Speaker's neutral role.
• The clear winner from the feud is the DPP, with several figures warning the KMT is burning itself out and helping President Lai toward re-election.

Outlook: The rift between Han and Fu over the budget timeline and the KMT's leadership direction is likely to keep widening, deepening the party's internal split ahead of 2028.
