"We will utilise his abilities in one form or the other in the party," he said.
Asked if any disciplinary action will be taken against Jaswant Singh, the BJP chief said the question was "hypothetical".
Jaswant Singh represented Darjeeling in the outgoing 15th Lok Sabha. The BJP ticket for the constituency has now been given to S.S. Ahluwalia.
Jaswant Singh wanted to contest from Barmer but the party fielded Col. Sonaram, who recently switched to the BJP from the Congress.
Following protests from BJP workers against the denial of ticket to Jaswant Singh, a meeting was held at the home of the former union minister's son Manvendra Singh Friday night.
His supporters in Barmer have chalked out a strategy to field him as an Independent.
Some party workers took out a protest rally and burnt effigies of Rajasthan Chief Minister Vasundhara Raje, holding her responsible for the denial of ticket to Jaswant Singh. They also shouted slogans against her.
"Col. Sonaram was with Congress for years. Now he has switched loyalties and joined the BJP. Fielding him immediately after joining the BJP has sent a wrong message to the voters. He should have been made to work in the organisation at least for some years before he was given such an opportunity," said a local BJP leader.
If Jaswant Singh decides to contest, he may upset the equation against Sonaram as there are at least 1.5 lakh Rajput voters in Barmer constituency, experts said.
"He has influence over voters from other castes also. So Jaswant Singh will definitely make life difficult for the BJP candidate," said political analyst Vijay Sharma.
Voting for the 25 parliamentary constituencies in the state will take place April 17 and 24. In the 2009 elections, the Congress won 20 seats and the BJP four while one seat went to an Independent.
Jaswant Singh hails from Jasol village in Barmer district. He was a member of the union cabinet during the BJP-led National Democratic Alliance government.
