Protest leader Suthep Thaugsuban is leading demonstrators from all rally sites in Bangkok to the Office of the Defence Permanent Secretary today to strengthen pressure on embattled caretaker Thailand’s Prime Minister Yingluck Shinawatra.He called on People’s Democratic Reform Committee (PDRC) supporters to drive their cars to pick up fellow demonstrators and deliver them to Muang Thong Thani where the Office of the Defence Permanent Secretary is located.Yingluck has used the Office of the Defence Permanent Secretary as her temporary office since protesters seized Government House and blockaded all entrances.The PDRC’s plan to rally at the Office of the Defence Permanent Secretary coincides with farmers’ planned demonstration to demand rice payments from the state subsidy scheme.Farmers who have been rallying in front of the Commerce Ministry announced that they would return to the Office of the Defence Permanent Secretary today after their talks with caretaker Deputy Prime Minister/Finance Minister Kittiratt Na-Ranong on overdue payments failed.Suthep urged protesters to drive their cars to the four rally venues, Pathumwan, Ratchprasong, Asoke and Lumpini, to take others along since Muang Thong Thani would be too far to walk from the city centre.Suthep claimed that he was contacted by a person who told him that Yingluck would be willing to resign on the condition that she approves a candidate as the next prime minister, according to (MCOT online news).Four protesters, one policeman were killed and 66 others injured in the police crackdown at Phan Fah Bridge and nearby Ratchadamnoen Avenue.
