"We will definitely raise our voices if any party tries to settle its political vendetta and does something," Delhi Congress Chief, Arvinder Singh Lovely, told reporters.
Referring to AAP's stand against corruption, Singh said that it was the duty of every Chief Minister to fight corruption.
"It is the duty of the chief minister and everybody concerned to fight corruption. When they take oath, they also take an oath to fight corruption. It does not necessarily have to be mentioned in election manifestos," he said.
Meanwhile, reiterating that there was no change in the Congress stand of backing AAP in government formation, Singh said the party will only extend its support to the new dispensation in the Legislative Assembly.
"Senior Congress leader Shakeel Ahmed and former Delhi Congress chief JP Agarwal had written to Lt Governor Najeeb Jung on December 13 stating that Congress was extending outside support... We are sticking to that," Singh said, adding that a meeting of the Congress Legislative Party is to be held to discuss their strategy in the Assembly.
On the question of AAP writing to Congress President Sonia Gandhi to elicit the party's stand on the 18 points raised by it, Singh said that it has been clarified that most of those issues were related to executive decisions which any party in power was free to adopt.
