On Sunday, September 18, 2011 the United Front for Democracy against Dictatorship and its affiliated groups commemorated the five-year anniversary of the military coup of September 19, 2006 that ousted prime minister Thaksin Shinawatra.

Reportedly, 15,000 red shirts convened on Ratchadamnoen Road around Democracy Monument in the afternoon to hold speeches and perform songs. While many red shirt leaders, some of whom became MPs in the last election, were in Cambodia to meet with Thaksin, some leaders like, Thida Thavornseth, Dr. Weng Tojirakarn and Nattawut Saikua did appear on stage.

As with all Red rallies since the 2006 coup, folk music, protest anthems and dancing were the order of the day. (Photo by Lillian Suwanrumpha)

The usual Thai media outlets were present yet there were very few foreign correspondents to be seen. Ongoing violence in the South and current negotiations with Cambodia largely overshadowed news of the mass gathering. (Photo by Lillian Suwanrumpha)

However, it didn’t stop Wiputalaeng Wattapoomtai, once charged for terrorism by the previous Democrat government for his role in last year’s protests, from continuing proceedings. (Photo by Lillian Suwanrumpha)

Police were present as usual, though there was little tension. (Photo by Lillian Suwanrumpha)

Away from the main stage, poetry, song and comedy hosted by the Somyos’ 24th June Democracy Group and others tackled relatively “sensitive” issues. Somyos Prueksakasemsuk is currently in jail on Lese Majeste charges. (Photo by Lillian Suwanrumpha)
