"Uddhav ji has decided to attend the dinner to be hosted by Modi ji tomorrow," Sena MP Sanjay Raut told PTI.
A Sena leader termed the dinner invite as Modi's diplomacy in which he will try and get consent over a name for the Presidential election slated in July.
All members of Lok Sabha, Rajya Sabha and state assemblies are voters in Presidential polls.
"Though the BJP has majority in Lok Sabha and it is in power in several states, they do not want the allies to give any reason to complain. That is why Modiji is to host the dinner," said sources from the party.
