NLN protesters Pumiwat Rangkasiwit and Siranya Thongchuea were joined by activist Somyot Pruksakasemsuk, who offered them moral support.
Prime Minister Prayut Chan-o-cha and his accomplices had worsened the economy and widened the gap between rich and poor since coming to power in the 2014 coup, Pumiwat said.
The government should solve people’s economic problems during the virus crisis by issuing practical measures to help the unemployed, said the protesters.
They also demanded that the government be more responsive to people’s wishes and to public participation.
“You must listen to us or resign!” they said.
Their petition was received by the Prime Minister's Office’s vice minister, Suporn Atthawong, who invited the leaders to discuss their demands.
