A group of some 100 students from 30 schools called on Thailand's Prime Minister Thaksin Shinawatra to resign, just after four of the Prime Minister's fellow party members urged the same.
The students, according to The Nation daily, called themselves the Fellowship of Secondary Students for Democracy. They said Thaksin was the source of all problems affecting Thailand now.
The students said that if Thaksin did not resign by Feb 26, the group would gather signatures of secondary school students nationwide to tell him to step down.
Earlier Tuesday (Deb 21), four Thai Rak Thai party members urged their Prime Minister to quit, breaking rank for the first time.
Thaksin had earlier said he would dissolve parliament and force new elections if political pressures on him become too strong, but that he will not resign.
