The detention of Chang Chao-lung, an independent candidate for the New Taipei City Council, on suspicion of vote-buying is a heavy blow to the Taiwan People's Party's image.

• Chang is accused of handing out turnip cakes and US dollars at community events to solicit votes; prosecutors consider the suspicion of bribery and misappropriation of charitable funds to be substantial.
• New Taipei prosecutors, concerned that he might destroy evidence or collude on testimony, applied for detention incommunicado, which the court approved.
• The turnip cakes came from a sheltered workshop, meaning supplies belonging to a organisation serving disadvantaged people were used as election bargaining chips.
• Academics have criticised the TPP for repeated cases of knowingly breaking the law, and say this is unlikely to be the last one.
• The key to determining vote-buying lies in the "quid pro quo" relationship: whether the candidate intended to exchange gifts for votes, and whether voters felt obliged to vote for him after accepting them.

Outlook: With the case entering the investigation stage and the election season approaching, similar disputes over gift-giving to solicit votes are likely to surface again.
