New Delhi, May 19 - As the talk of Presidential elections gains ground, BSP chief Mayawati today kept everyone guessing on her choice saying UPA or NDA were yet to declare their nominees and she would back a candidate who fits into her party's "line of movement".

"Our party is keeping an eye on all the parties on the issue of the Presidential nominee. Let us see what candidate UPA and NDA field," she told reporters here when asked about the Presidential elections.

She said the BSP would take a decision once the UPA and NDA nominees were clear.

"As soon as the candidates of the UPA and NDA are clear, we will take a decision to support a candidate who suits our party's line of movement," the former Uttar Pradesh Chief Minister said.

She parried a question on whether the BSP would support Finance Minister Pranab Mukherjee if he enters the fray as the UPA candidate.

"When it is not clear who is the candidate of UPA or NDA, what should I say about the merits or demerits of a particular candidate. Whichever candidate comes before us, we will see whether he suits our party's line of movement. We will support whoever fits in our party line of movement," Mayawati said.

Asked about BJD and AIADMK announcing NCP leader P A Sangma as their choice for the top Constitutional post, the BSP chief said she had heard about it only through media reports.

BSP has 21 members in the Lok Sabha and 15 members in the Rajya Sabha. The party has 80 members in the Uttar Pradesh Assembly.

The value of its vote in the electoral college for the Presidential elections is 43,723. The total value of the electoral college is 10,97,012.

The electoral college for the Presidential election consists of the elected members of Lok Sabha, Rajya Sabha and all Legislative Assemblies.

Asked whether the BSP will be a part of a non-UPA, non-NDA alliance, Mayawati said her party will not fall in such traps.

"Our party has not thought about it. We are not going to fall in such traps," she said.

On the Lokpal Bill, Mayawati said the Centre has to give final shape to the Bill and bring it before Parliament. PTI
