Lakhisarai/IBNS/UNI: Union Home Minister Amit Shah Thursday dubbed Rahul Gandhi as a "failed leader" who has been continuously launched unsuccessfully by Congress for the last twenty years.

Addressing a public meeting at Lakhisarai in Bihar, Shah also described the state chief minister Nitish Kumar as a leader who has "lost his credibility".

Shah said Congress was trying to launch Rahul Gandhi for a long time without any success as people were "not prepared to accept him".

"It is for the first time in the history of any political party that a particular leader is being launched for two decades," he quipped.

Sah said the recent meeting of the anti-BJP parties in Patnawas yet another attempt of the Congress to launch Gandhi.

"In BJP, no leader has ever been launched by the party, but it is the people who have launched a leader of BJP", the Union Minister and senior BJP leader said.

He said both Gandhi and Kumar were dreaming to become the Prime Minister.

"In reality, Kumar is befooling the RJD president Lalu Prasad at this advance age as he is not going anywhere and would remain in Bihar," he pointed out while making an oblique reference to the "promise" made by Kumar to Lalu that he would pave the way for Deputy Chief Minister Tejaswi Prasad Yadav to become Chief Minister, by himself switching over to national politics.

Shah said that Kumar has "lost his credibility" by changing "home" frequently, alluding to the chief minister changing his allies several times.

"People have never accepted a leader who frequently changed his home," he said.

Kumar had changed his loyalty to the NDA and Grand Alliance three times since 2013.
