'Political purge' on Hong Kong opposition may spell end of democracy

Decision to bar pro-democracy candidates is a sign that even moderate dissent will not be tolerated

Hong Kong's decision to bar 12 pro-democracy candidates from standing for office sets a sweeping precedent and may signal the end of meaningful political opposition in the city.

The group disqualified from contesting upcoming elections to the city's legislative council include the prominent student activist Joshua Wong but also moderates and four incumbents, such as Alvin Yeung, who represents Hong Kong's accountants.
