The Palang Pracharath Party (PPRP) has touted Prime Minister Prayut Chan-o-cha's achievement in maintaining peace and order in a last-ditch attempt to woo voters.
A new advisory team of Gen Prayut comprising six experts with credentials in the field of economics were appointed in what is seen as an effort to restore the confidence of voters just three days before the election.
They are Disthat Hotrakit, ex- secretary-general for the Office of the Council of State; Boontuck Wungcharoen, former chief executive officer of TMB Bank; Piti Tantakasem, current chief executive officer at TMB Bank; Sethaput Suthiwart-Narueput, member of the Bank of Thailand's Monetary Policy Committee; Supattanapong Punmeechaow, president of PTT Global Chemical Plc; and Deputy Transport Minister Pailin Chuchottaworn.
The Prayut administration has been criticised for its handling of the economy during its more than four years in office. It is believed that the new advisory team will restore the confidence of voters, observers noted.
"They have been officially appointed and if Gen Prayut returns as PM they will continue to support him as his team of economic advisers," a government source said.
The PPRP will hold a final rally today as all eyes are on whether Gen Prayut will appear on the rally stage to help with the party's campaign in its last lap.
In the final leg of its campaign, the PPRP has sent video clips featuring Prime Minister Prayut, its prime ministerial candidate, to be screened at the party's rally stages.
The PPRP has also highlighted the regime's success in keeping peace and order during the past five years as its major selling point.
The PPRP has adjusted campaign posters in Bangkok with the pictures of candidates and Gen Prayut by adding stickers with the message "Choose Peace, Uncle Tu's your answer".
Peace and stability are one of PPRP's major campaign policies. If the country is peaceful, other policies, particularly economic measures, can be implemented successfully. Gen Prayut has what it takes to get the job done during the transitional period, according to the PPRP's Facebook page.
Meanwhile, other parties such as the Pheu Thai and the Democrats have stepped up their campaigns focusing on stopping the regime from returning to power after the election.
Pheu Thai has stepped up its campaign urging people to vote for the party to stop the regime from returning to power. The party said it needs as many votes as possible to beat the 250 appointed senators which can join MPs to choose a prime minister.
The Democrat Party on Thursday released a video clip featuring its leader Abhisit Vejjajiva wooing voters.
Mr Abhisit said that every single vote from across the country will boost the party's House seats and this will help cut off "the vicious cycle of dictatorship and corruption".
Major political parties have rolled out a new raft of policies to attract voters as they plan their final large rallies ahead of Sunday's general election.
The Pheu Thai Party has come up with its latest campaign policy called "a savings lottery scheme", hoping to win the hearts of the people.
Khunying Sudarat Keyuraphan, a Pheu Thai prime ministerial candidate, said the proposed scheme is aimed at encouraging personal savings through the purchase of a lottery ticket each month.
She said the money paid would not be "missing" but would become savings with interest and dividends and holders of the tickets are also entitled to win the two- and three-digit prizes. People can buy the lottery starting at the age of 20 until 60 and accounts will also be required to buy lottery tickets. Tickets will be sold for 50 baht each, Khunying Sudarat said.
In a video clip released by the Pheu Thai, the party further explained that the savings will be invested in the National Savings Fund after subscribers reach 60.
Other campaign policies offered by the Pheu Thai include the second phase of the 30-baht health care programme, said Chadchart Sittipunt, another Pheu Thai prime ministerial candidate.
Pheu Thai today plans to hold its final major campaign rally at the Thai-Japan Bangkok Youth Centre in Bangkok's Din Daeng district from 4pm onwards.
Mr Chadchart said that even though the venue can hold only 3,000 to 4,000 people, the event will be broadcast nationwide via the internet and other electronic media.
Pheu Thai deputy spokesman Jirayu Huangsap said party key figures will campaign on pickup trucks to woo voters in all of Bangkok's districts tomorrow.
However, Yutthaporn Isarachai, a political scientist from Sukhothai Thammathirat Open University, said most voters already have in mind who or what party they will vote for and that political parties' last-ditch campaign pledges will have little bearing on voters' decisions.
Suthep Thaugsuban, founder of the Action Coalition for Thailand Party (ACT) and former leader of the now-defunct People's Democratic Reform Committee (PDRC), on Thursday posted on Facebook, saying that former supporters of the PDRC should think carefully before deciding on who to vote for.
