The unprecedented move came after the MPs repeatedly disrupted proceedings with some of them also serving notices for a no-trust motion, causing embarrassment to the party and the government.
The action itself came hours after L Rajagopal and Sabbam Hari, along with members of YSR Congress and TDP, gave such notices today.
Hari even threatened to commit self-immolation in Lok Sabha if the Bill to carve out a separate Telangana state from Andhra Pradesh was introduced.
Along with Hari and Rajagopal, the MPs expelled by Congress President Sonia Gandhi are GV Harsha Kumar, V Arun Kumar, R Sambasiva Rao and A Sai Pratap.
