BJP President Rajnath Singh today challenged Congress to declare its prime ministerial candidate before losing sleep over the nominee of his party. "Will the Congress dare announce who will be the prime minister candidate before the general elections?" he said.

Claiming that there are too many contenders for the job in the Congress Party '" Sonia Gandhi, Rahul Gandhi, Manmohan Singh, P Chidambaram and other unnamed dark horses, Singh said Congress leaders and workers are confused as to who would be the next prime minister if their party returns to power.
