Assam chief minister Tarun Gogoi had taken moral responsibility and so had other Congress chief ministers and offered to resign for their party's poor performance, senior BJP leader Sushil Kumar Modi told reporters here.
"Nitish must take moral responsibility for the rout of his party in the general elections and resign as the Bihar Chief Minister," he said.
A staggering 80 per cent Lok Sabha seats going to the kitty of the BJP-led alliance clearly pointed to verdict against Kumar, the former deputy chief minister said.
"Should not you abide by protocol and pick up phone to congratulate your Gujarat counterpart over his electoral victory?" the former deputy chief minister asked.
"We have registered a landslide victory in the general elections due to Modi's leadership and charisma," he said.
Modi also said that his party would not try to dislodge the state government, but at the same time claimed that a number of ruling party MLAs were in touch with the BJP and even worked for their victory.
