Amid the massive pro-democracy protests in 2019, Junius Ho who was a key anti-protest figure who was allegedly involved in the Yuen Long attack was challenged by Democratic Party's Lo Chun-yu in his constituency in the November election, with Lo's party winning eight seats. A historic landslide victory occurred as the pro-democrats took 28 of the 31 seats in the council with Ho being unseated. A localist political group Tuen Mun Community Network also grabbed four seats as a result.
