"BJP has provided moral support to both Anna Hazare's and Ramdev's campaigns in the past and is even ready to lend active support to the yoga guru's stir if he approaches the party for it," former BJP president Rajnath Singh told reporters here.
Any endeavour to eradicate a social evil must be backed by all, he said.
Ramdev today launched a three-day fast along with his supporters demanding immediate action to enact a strong Lokpal and steps to bring back black money stashed away in foreign banks failing which he will announce his future strategy.
Singh claimed that BJP would emerge as the single largest party in the 2014 Lok Sabha elections.
To a question whether Bihar Chief Minister Nitish Kumar was enforcing pressure on the BJP to declare a Prime Ministerial candidate, he said "Nitish is an ally of the NDA."
The Centre needs to take some effective steps to end the financial crisis and deal with the internal security concerns, the BJP leader said.
