Thousands of protesters are gathering in Taipei as opposition lawmakers try to push through controversial legislation giving them greater investigative powers and effectively curbing the authority of President Lai Ching-te.

Anger at the measures sparked violent shoving matches inside the legislature Tuesday, as people again assembled in the streets around the parliament amid concern the opposition Kuomintang (KMT) and its Taiwan People’s Party (TPP) allies will pass the legislation.

Last week’s protests were among the largest since the 2014 Sunflower student movement, when protesters stormed and occupied parliament to block the passage of an unpopular trade pact with China.
