The Future Forward Party (FFP) will next week announce the outline of its role as an opposition party "both inside and outside parliament", spokesperson Pannika Wanich said on Friday.
Before the announcement, it will hold an event on Saturday at Thammasat University's Tha Prachan campus to mark the first anniversary of the party's founding. At the event, the party will host a forum called "Walk with me, talk with me" and musical performances, as well as hold fundraising activities and recruit new members.
Party leader Thanathorn Juangroongruangkit and secretary-general Piyabutr Saengkanokkul are also due to deliver speeches outlining their political vision. Other key speakers who will attend the party's activities include TV host and writer Wannasingh Prasertkul, actor Karoonpon "Petch" Tiensuwan, Rangsit University's political science lecturer, Asst Prof Thamrongsak Petchlertanan, as well as "Ajarn Boy", administrator of TootsyReview Facebook page.
Several thousand participants are expected at the event, a party source said.
The Constitutional Court last month suspended Mr Thanathorn as an MP pending its ruling on whether he breached media shareholding rules.
In a separate development, activist Srisuwan Janya has filed a petition with the Election Commission to probe claims made by 13 Future Forward MPs that they had been offered up to 120 million baht each to switch sides and vote for Gen Prayut Chan-o-cha as prime minister.
Thirteen FFP MPs said at a briefing on Tuesday they had been offered 30-120 million baht each to vote for Gen Prayut instead of Mr Thanathorn on Wednesday. During the prime ministerial vote, none of the FFP's MPs voted for him. Such an act of bribery violates Section 149 the Criminal Code and Sections 28, 29, 44, 46 and 88 of the 2017 Political Parties Act, the activist said.
"It's an act akin to toppling the rulers of the country or acquiring power through means other than what is prescribed in the constitution and is grounds for the dissolution of a party," he said.
Mr Srisuwan urged the FFP to take legal action against those who allegedly made the offers without delay. "This is to clear its [the FFP's] name and criticism that it held the briefing for political gain ahead of the prime ministerial vote," he said.
Failure to do that could lead to the removal of its executives. They could be fined 50,000 baht each and banned from politics for five years, he added.
On Thursday, Taopiphop Limjittrakorn, one of the MPs who made the claim, said he was not sure what he had said at the briefing implicated or adversely affected Mr Srisuwan in any way.
"I insist I was offered 120 million baht and several of my fellow MPs who were also approached have evidence. It's up to the party whether we should disclose the evidence, such as audio clips. If the party allows us to show evidence, I'm ready to do so," he said.
Separately, anti-coup activist Ekachai Hongkangwan wrote on Facebook that parliament is now sitting and the FFP should focus on actual work, not create "dramas".
