The Bhumjaithai Party believes it could surprise many by winning constituencies in the South in the upcoming March 24 election.
Bhumjaithai spokesman Settapong Malisuwan said the party will hold campaign rallies in Nakhon Si Thammarat today and Phatthalung tomorrow.
"Bhumjaithai can be a surprise winner in various southern provinces," said Mr Settapong. "Key southern figure Natee Ratchakitprakarn and party candidates have been working hard and staying close to residents there."
Responding to several opinion polls in which Bhumjaithai leader Anutin Charnvirakul was not named among the most popular prime ministerial candidates, Mr Settapong said each poll is different and some do not reflect the reality.
"There is no need to make any change in the party," he noted, insisting his party is known across the country and its policies have received favourable feedback.
Meanwhile, Suwat Liptapanlop, chief adviser of the Chart Pattana Party, led a rally in the southern province of Chumphon yesterday.
Party members and candidates visited the construction site of the Chumphon deep-water seaport, where they met fishermen and farmers to hear their problems.
They also touted a "Riviera" tourism development project along the coastlines of the Gulf of Thailand and Andaman Sea and voiced their support for increasing the ratio of palm oil in diesel fuel to boost the crop's prices.
Meanwhile, the pro-regime Palang Pracharath Party (PPRP) held a large event in Kanchanaburi's Tha Muang district on Friday evening.
They vowed to offer a three-year debt moratorium on loans from the Village Fund, tackle falling crop prices and speed up the issuing of land documents.
At the event, attended by 20,000 people, Ekasit Kunananthakul, a PPRP MP candidate for Kanchanaburi, said: "I am confident that the party will win all the five constituencies of Kanchanaburi."
