The protesters started to move from the Lat Phrao intersection at 10am.
They are moving along Phahon Yothin road to Kasetsart University, after which they will return to Ratchayothin intersection and then turn left along Ratchadapisek road.
The protesters are expected to return to Lat Prao intersection shortly after midday since Mr Suthep is scheduled to attend the funeral of Prakong Chuchan, a PDRC guard who was seriously injured by a bomb on Banthat Thong road on Friday and pronounced dead in hospital on Saturday morning. The funeral is being at Wat Thepsirintarawat.
The protesters at the Lat Phrao intersection were joined in the march by others led by Luang Pu Buddha Issara from the Chaeng Wattana rally site.
