"The BJP should not mind taking outside support of like minded legislators to form a government if the JD (U) government collapses after the end of the Lok Sabha polls," he said here.
Thakur said he expected many Janata Dal (United) legislators to desert the now ruling party if it performs poorly in the Lok Sabha battle.
"The government is already in a minority. After the election, it is bound to fall,” he said.
BJP leader and former deputy chief minister Sushil Kumar Modi had earlier this week said that over 50 JD-U legislators were in touch with his party as they were unhappy with Chief Minister Nitish Kumar.
