Anti-government protesters, including those in some provinces with Pheu Thai Party and red-shirt strongholds, rallied across the country to join the Democrat-led protests in the capital against the Yingluck Shinawatra government.
The prime minister's announcement yesterday morning that the government had decided to dissolve the House didn't discourage thousands of rally-goers from hitting the streets.
Many marched to provincial halls and blew whistles to protest against the caretaker government.
The House dissolution can only relieve the political turmoil in the short run, predicted Songkhla Chamber of Commerce chairman Somphon Siriporananon.
"People have walked for so long" that the new elections which will result would not be enough, he said.
New regulations accepted by people must be set up to pave the way for freeing Thailand from corruption, he said.
"We then can enter an election process which is pure and clean," Mr Somphon said as business people in Songkhla marched to support their campaign against corruption yesterday.
Rally-goers in other provinces also called for big changes in politics.
In Pheu Thai-dominated Nakhon Ratchasima, about 3,000 anti-government protesters rallied at the provincial compound, calling on officials to stand by the people, not politicians.
Various venues, including provincial halls in northern provinces, in Sukhothai, Phitsanulok, Mae Hong Son and the Pheu Thai-stronghold of Phayao, were also filled with hundreds of whistleblowers.
Rayong and Chon Buri protesters in the East, and Ratchaburi protesters in the West also turned out.
The atmosphere was lively in the South where several thousand protesters in Chumphon, Surat Thani, Nakhon Si Thammarat, Phuket, Trang and Yala provinces gathered at provincial halls to make their voices heard.
In Nakhon Si Thammarat, high schools and vocational schools suspended classes to let students join the rallies to experience "lessons" in political participation.
