Patna, May 23 (IANS) The BJP would not join hands with Bihar Chief Minister Nitish Kumar ahead of the state assembly polls, former deputy chief minister Sushil Kumar Modi said here on Saturday.

"There was no possibility of friendship or an alliance of the BJP with Nitish Kumar...," Modi told reporters.

He said Nitish Kumar was not reliable. "We had experienced it," he said.

The BJP leader said RJD chief Lalu Prasad has realised that Nitish Kumar will betray him and the Congress anytime.

"Afraid of the BJP, Nitish Kumar joined hands with Lalu and eager for merger of his party JD-U with the RJD. But it has failed now," Modi said.

Modi said if Nitish Kumar can betray the BJP after 17 years of alliance and sharing power in the central and state governments, he can do the same with others.

Bihar is going to the polls later this year.
