The UPA government had been in the ICU after the DMK's exit, SAD chief and Punjab Deputy Chief Minister Sukhbir Singh Badal said at a function in Ludhiana.
"With the DMK withdrawing support to the UPA and Mulayam Singh Yadav-led Samajwadi Party breathing down its neck, early polls to the Lok Sabha are inevitable," he said.
"The government is in ICU and day-to-day supply of oxygen cylinders cannot keep this brain dead government alive for long," Badal said, according to an official release here.
The DMK today withdrew its support to the UPA government and pulled out its five ministers over the issue of alleged human rights violations of Tamils in Sri Lanka.
