Taiwan's main opposition party pulled out of the National Assembly Monday and vowed to take to the streets in huge demonstrations demanding faster democratic reform.

Democratic Progressive Party officials said public protest was the only way the party could fight the ruling Nationalist Party's plans to let aging party stalwarts make constitutional changes."This decision was made to protest all the recent actions by the Nationalist Party," deputy secretary-general James Chen said by telephone, adding that DPP members in the separate legislature and local assemblies also planned to stage walkouts.
