New Delhi/Jaipur: Former Congress president Sonia Gandhi is set to enter Rajya Sabha for the first time and will file her nomination papers from Rajasthan for the upcoming polls to the Upper House, party sources said on Tuesday.

Barely two months before the Lok Sabha election, Gandhi will be filing her nomination papers in Jaipur on Wednesday. Party chief Mallikarjun Kharge, her son Rahul Gandhi and daughter Priyanka Gandhi Vadra are likely to accompany her.

Gandhi, who represented Rae Bareli in Lok Sabha, will not contest the next general election. She has been a five-term Lok Sabha MP and was first elected in 1999.

“She is likely to file nomination for Rajya Sabha on Wednesday,” a source said.

A total of 56 members of Rajya Sabha from 15 states are retiring in April and the election to the seats will be held on February 27. The last date for filing nominations is February 15.

The Congress is comfortably placed to win one of the three Rajya Sabha seats from Rajasthan for which elections will be held. The seat will fall vacant after former prime minister Manmohan Singh completes his six-year tenure in April.

She will be the second member of the Gandhi family to enter Rajya Sabha after former prime minister Indira Gandhi, who was a member of the Upper House from August 1964 to February 1967.
