According to reports, the two leaders met for a few minutes and were understood to have discussed the current political situation and a possible alliance between the two parties in Bihar.
Although, Rahul reportedly does not personally favour to form an alliance with Lalu's RJD because of two reasons. First, Lalu recently got bail in fodder scam case in which he was convicted and secondly, forming an alliance with the RJD may raise doubts on Rahul's stand on corruption.
However, as the Lok Sabha elections 2014 are fast approaching, Lalu has been showering praises on the Congress' scion.
Lalu has been showering praises on the Congress v-P Rahul Gandhi.
During last month visit to riot-hit Muzaffarnagar in UP, Lalu said that the BJP's prime ministerial candidate Narendra Modi and Delhi Chief Minister Arvind Kejriwal are 'nothing' in front of Congress party's Vice President Rahul Gandhi.
Earlier, Lalu had met Congress chief Sonia Gandhi and vowed not to repeat the 2009 mistake of allowing the breakdown of alliance between RJD and Congress.
Lalu Prasad is likely to meet the Congress chief again later this month for working out details of a possible alliance.
He had earlier said he has full confidence that an alliance of Congress-RJD-LJP will happen this time and will halt the march of "communal forces" in Bihar, Jharkhand and elsewhere.
He had also praised the leadership of Rahul Gandhi as "million times better" than that of Narendra Modi and Arvind Kejriwal.
LJP and RJD had fought 2009 Lok Sabha elections separately without an alliance with Congress and as a result while RJD could win only four seats in Bihar, Congress two and LJP failed to open its account.
