Congress president Rahul Gandhi on Friday said he was unaware of any speculation about BJP leader Varun Gandhi joining his party.
The Congress chief's remark comes two days after his sister Priyanka Gandhi Vadra formally entered politics on Wednesday ahead of the elections.
"I have not heard this speculation," Mr Gandhi said while responding to a query about Varun Gandhi joining Congress in a move to reunite the Gandh-Nehru family.
Varun Gandhi, cousin of Rahul Gandhi, is at present a Bharatiya Janata Party (BJP) Lok Sabha member from Sultanpur in Uttar Pradesh.
His mother Maneka Gandhi is the Union Cabinet Minister for Women and Child Development in the Narendra Modi government at the centre.
