He made the announcement while addressing a large crowd of protesters at the Lat Phrao intersection.
He urged supporters of the People's Democratic Reform Committee (PDRC) in the provinces, who have sufficient numbers and are ready to rise up, to close all government offices, starting with 14 provinces in the southern region and followed by those in the Central Plains, North and the Northeast.
He said daily gun and bomb attacks against the PRDC demonstrators had failed to scare the protesters and the more that violent incidents occurred, the more people would take to the streets to protest against the government.
“We have made it clear that we will fight peacefully. But they do it [violent attacks] to us every day. We have lost the lives of three of our brothers from gun and bomb attacks. We must not let their lives be lost in vain. We need to fight harder to eliminate the Thaksin-regime,” Mr Suthep said.
He also vowed to step up activities next week to ensure all state agencies in Bangkok are completely closed.
“The Bangkok shutdown has made an impact on the government after one week and five working days, but state officials were forced to work elsewhere from here and there. Therefore within the next week, we need to close all [offices], and not let them be a tool of the Thaksin-regime,” Mr Suthep said.
The PRDC secretary-general also announced the mobilisation of protesters to surround the homes of caretaker Prime Minister Yingluck Shinawatra and her ministers and cut off tap water and electricity this week.
