Blaming Opposition for the absence of proper power supply here, Priyanka said her "hands are tied" because of a court case in the matter.
Addressing an election meeting attended mostly by women here, she said the party has made many efforts to provide 24 hours power supply but despite that it could not do so.
"Power supply is the state government's responsibility. After Mulayam Singh government assumed power in UP, Soniaji and Rahulji approached him for continuous power supply in Rae Bareli and Amethi. Mulayam Singh decided immediately to provide power to these areas.
In a veiled attack on BJP's Smriti Irani, she charged, "A candidate has come here. Her party people filed a case and got round-the-clock power supply stopped."
"It was asked in the case as to what was special about these two areas that power should be supplied for 24 hours. That is why the case is stuck here and our hands are tied. Until the case is resolved, 24-hour power supply cannot be resumed," she said.
Targeting women voters, she said, "This is election time and one should say what can be done for women empowerment."
She also said the election fight should be done on "principles" and it should be done openly and not in a clandestine manner.
In a bid to strike an emotional chord with voters, she said, "I will not ask for your votes. I want your love. You have stood by our side in good times and bad times. We will be with you all the time."
"This is Amethi. I am coming here since childhood and I will keep coming when I will become old also," she said.
