A recall vote for a high-profile mayor is stirring political acrimony in Taiwan, with accusations of voter intimidation and official interference, and could bring new problems for the main opposition party, already reeling from losing January elections.

Kuomintang (KMT) soundly lost the presidential and parliamentary polls. Since then, under a youthful new leader, Johnny Chiang, it has tried to rethink its unpopular policy of seeking closer ties with China.

Now it faces further headaches if its defeated presidential candidate, Han Kuo-yu, loses a recall vote for mayor of the southern city of Kaohsiung, a major port whose leadership post he unexpectedly won in late 2018.
