"There was no need for the BJP members to threaten that they will resign, instead they should quit without any ado," Singh said.
Bye-elections would be held in all the constituencies represented by the members in case they resign, he said while claiming that even in the worst situation, the "Congress will win at least 20-30 seats presently held by the BJP."
The Opposition party was not doing a good thing by forcibly stalling proceedings in Parliament, he said.
