Groups protesting what they called high-level governmental officials’ lack of political responsibility toward an adulterated cooking oil scandal yesterday clashed with police in front of the Executive Yuan, while calling for both President Ma Ying-jeou (馬英九) and Premier Jiang Yi-huah (江宜樺) to step down.

Taiwan Adequate Housing Association president Huang Yi-chung (黃益中) said that the Executive Yuan’s plans to establish a food security office was “a joke” and the nation would be much better off if Jiang resigned from office.
