In his complaint, Singh asks whether helicopter expenses incurred by BJP leaders visiting Barmer constituency were billed to local BJP candidate Col Sonaram Choudhary.
Jaswant Singh is contesting as an independent candidate from Barmer. His fallout with BJP happened after the party refused to allot his a ticket from Barmer, his home town.
Senior party leaders, including Rajasthan CM Vasundhara Raje and Modi had made frequent trips in and around Barmer during the campaign period to ensure the victory of the party candidate, a former-Congress man.
"When Rahul Gandhi visited Tonk, the helicopter expenses were included in the local candidate's expenditure limit. So if Raje is frequently visiting Barmer and Jaisalmer and Modi is slated to visit Barmer, why should it not be included in the BJP candidate's expenditure cap too?", asked Singh.
"Barmer is not a tourist spot. But there is no saying what political communities will do these days," he added.
The BJP senior leaders are extra-cautious to ensure party candidate's victory in Barmer. Modi had held a rally at Ratkudiya in Pali constituency, close to Barmer, on Monday and will be back on Saturday for a rally in Pachpadra.
Jaswant will release his own manifesto on Thursday, one that he a calls a "candidate's agenda". "It will not have an elaboration of the country's nuclear policies and such other esoteric themes but entirely local issues," he said.
