New Delhi: With Priyanka Gandhi consenting to campaign for the Congress in the upcoming 2017 UP assembly elections, the Bharatiya Janata Party (BJP) trained its guns on her brother and Congress vice president Rahul Gandhi, saying the development clearly indicated that his credibility was in question.

According to reports, Priyanka will begin her campaign with an event in Allahabad on the 99th birth anniversary of former Prime Minister and her grandmother Indira Gandhi.

BJP spokesperson Siddharth Nath Singh said the Congress floats the name of Priyanka, whenever they feel Rahul's image is in trouble.

"Whenever the stock of Rahul Gandhi is down, the Congress floats this idea. All I can say is its shows that there is less credibility of Rahul Gandhi, therefore, Priyanka's name keeps coming up now and then," he said.

This comes after Congress confirmed that Priyanka will be promoting the party's agenda.

"Priyanka has agreed with our request. However, it is not decided as to when and where will she campaign," Congress leader Raj Babbar said.

Priyanka's presence in the Congress camp is expected bring new vigour into the grand old party's poll campaign in Uttar Pradesh, which has come under the attack from rival parties for being soft.

Priyanka Gandhi has so far campaigned only in Amethi and Rae Bareilly, known as the bastions of the Nehru-Gandhi family.

Several members within the Congress feel the party will greatly benefit from Priyanka's presence.

Last month, Congress vice-president Rahul Gandhi held a 26-day long "Kisan Yatra" in Uttar Pradesh to woo voters.
