"I have been given full assurance by the Congress president and (Congress vice president) Rahul Gandhi that the entire Congress leadership and resources will be behind me for this contest," said Amarinder, 72, who comes from the erstwhile royal family of Patiala.
Amarinder's wife, union Minister of State for External Affairs Preneet Kaur, is seeking re-election to the Patiala Lok Sabha seat on the Congress ticket.
This is the first time that the couple is contesting at the same time.
All 13 Lok Sabha constituencies in Punjab go to the polls April 30.
The ruling Akali Dal-BJP alliance in Punjab, which edged out sitting BJP MP from Amritsar, cricketer-turned-politician Navjot Singh Sidhu, from the seat and brought in Jaitley to contest for the `safe' seat could find the Amritsar election a tough political test.
