New Delhi, June 20: Rajasthan chief minister Vasundhara Raje has an even chance of making her first public appearance tomorrow since being sucked into the Lalit Modi controversy, an aide said today.

The aide said that Vasundhara, fighting an attack of spondylosis, had a "50-50" possibility of attending an International Yoga Day event her government would be holding in Jaipur's Sawai Mansingh Stadium.

Vasundhara had gone into a shell following revelations that she had lobbied the UK government in 2011 to extend Lalit's stay in Britain on condition that her role not "become known" to Indian authorities.

It's also been alleged that her son and MP Dushyant Singh had in 2008 clinched a "sweetheart deal" with Lalit, who invested Rs 11.63 crore into his hospitality company. The BJP, fearful of more skeletons tumbling out, has left mother and son to fend for themselves.

Vasundhara, the aide said, has been under the weather for the past few days because of spondylosis. Her physician was quoted as saying today that she was recovering, and that a decision on her presence at the Yoga Day event would be taken tomorrow morning.

The chief minister has been advised not to meet callers or spend too much time on the phone. Rajasthan BJP sources, however, said Vasundhara had been briefed over the phone about a meeting of party legislators today.

State BJP president Ashok Parnami had apparently scheduled the meeting 10 days ago, before the Lalit controversy erupted, to work out a strategy for the upcoming municipal polls in August.

A state BJP official said it was not a "show of strength" as was being speculated, for only those 129 MLAs whose constituencies housed the election-bound councils and wards had been summoned to the meeting.

"If it were a demonstration of the support the chief minister commands, all the 160 party MLAs would have been told to turn up," the BJP official said. He clarified that Vasundhara would anyway not have attended the meeting, which concerned the "nitty-gritty" of the local polls.

"For a while, after the media played up the Lalit controversy, we were afraid of the impact it might have on the municipal elections, especially if the chief minister's continuance came under question," a party MP said.

"Now we feel that she has received a breather because there is no evidence that she had signed the document (application for prolongation of his stay) that Lalit submitted to UK officials."

Even an intra-party Vasundhara critic claimed there was "no ground" for the Congress to seek her ouster except to score brownie points.

"Vasundhara's links with Lalit were known to the Congress and to us. When she was in the Opposition, the Congress ruled Rajasthan and the Centre," he said.

"What stopped their leaders from pursuing the cases against her? Why did they get cold feet after kicking up a rumpus initially?"
