Former Union Minister and Bharatiya Janata Party official spokesperson Shahnawaz Hussain on Sunday said his party would disclose its strategy on Presidential elections only after the ruling United Progressive Alliance coalition announces name of its candidate.

Until the ruling Congress party does not announces name of its candidate for the President's post, BJP would keep its cards close to its chest, Shahnawaz told reporters.

On whether BJP would support Finance Minister Pranab Mukherjee's candidature for the post of President, he said, "Let Congress party first name the candidate for the post, then only our party will disclose the strategy."

Stating that this time the presidential elections would be "interesting", he said it was not necessary that the ruling party candidate would be the winner.

"This time the presidential election results would be surprising and our party is working on this strategy," he said. Demanding an investigation into the alleged coal scam, Shahnawaz asked why the UPA government was afraid to order a probe when, according to them, there was no scam in allocation of coal blocks.
