The Samajwadi Party (SP) and the Rashtriya Janata Dal (RJD) on Monday said they had decided to withdraw support to the Congress-led UPA government over differences on the Women's Reservation Bill.

"We have decided to pull out. We have withdrawn our support to the government," RJD chief Lalu Prasad said outside parliament after an uproar in the two Houses over the bill that seeks to reserve 33 percent of legislative seats for women.
