Hosted by Prime Minister Manmohan Singh on the lawns of his official 7 Race Course Road residence, the dinner was graced by the members of all UPA allies, though the DMK was ill-represented with just one member.
The star attraction was UPA chairperson Sonia Gandhi, who was seen mingling freely with the guests.
