"Baba Ramdev is sitting on a fast at the Ramlila ground in Delhi. Whoever fights against corruption, he and his movement has our full support," BJP spokesperson Shahnawaz Hussain said.
BJP and RSS, along with other Sangh affiliates, have extended their support to Ramdev's fast. However, BJP was evasive when asked if it would participate in Ramdev's movement.
But some members close to the Sangh Parivar have joined the yoga guru at Ramlila grounds.
"We have extended moral support to him," Hussain said.
He maintained that it was senior BJP leader L K Advani who had first raised the issue of Indian Black money stashed abroad when he mentioned it during the 2009 Lok Sabha elections.
BJP also took potshots at Congress General Secretary Digvijay Singh, asking him to clarify whose "agent" he was and at whose behest he was making statements against Ramdev.
Singh had earlier alleged that Ramdev was an agent of the RSS.
"We never take Digvijay Singh's statements seriously. But now we do as he is speaking as an agent of somebody. He should clarify whose agent he is. He is general secretary of Sonia Gandhi," Hussain said.
He accused Congress of adopting double-standards and this had been seen earlier in the Shah Bano case.
