The meeting between Siddiqui and Paswan came a day before a meeting of LJP Parliamentary Board to take a call on the issue of alliance amid demands from some quarters within the party that LJP should also explore the possibilities of an alliance with ruling JD(U).
Sources said the meeting scheduled tomorrow may or may not take place indicating a thaw between the two parties.
Soon after he was out on bail after conviction in the fodder scam case, the RJD chief, who is keen on an alliance with Congress, came to Delhi and is likely to meet Congress President Sonia Gandhi. However, the meeting is yet to materialise despite Prasad having arrived here five days back.
Congress, RJD and LJP had contested the 2004 Lok Sabha election in an alliance winning 29 out of the 40 seats in Bihar. However, the alliance broke up in 2009 Lok Sabha polls when RJD had decided to offer three seats to Congress. Prasad had kept 25 seats RJD and gave 12 to LJP.
Soon after the results, murmurs had started in RJD that Paswan's party was given too many seats at the expense of Congress and that it did not put up strong candidates. Senior RJD leader Raghuvansh Prasad Singh never hid his opinion on the matter.
Sections in LJP believe the alliance can do better only if Lalu Prasad does not insist on contesting as many seats as his party had done the last time.
