The senators called themselves “senators who love the country." They announced at a press conference that Yingluck would be summoned to explain her speech to four Senate panels.
The four panels are the Senate committee on foreign affairs, the Senate committee on religions, ethics, arts and culture, the Senate committee on human rights and consumer protection, and the Senate committee on corruption and good governance.
The statement also accused Yingluck of telling only part of the story when she said former prime minister Thaksin Shinawatra was politically victimised.
The senators also called on Yingluck to take legal action against all officials in the Centre for the Resolution of Emergency Situation if innocent people had been killed by security officials during the crackdown on redshirt protesters, as the PM claimed in her speech.
