He was replying to a question whether the campaign by some fringe groups on the conversion issue would affect the development agenda of the Narendra Modi Government.
Asked repeatedly about the involvement of RSS in the matter, Shah evaded a direct reply and said, "RSS is a national organisation and I have no doubt over its activities."
Shah, who is on a two-day visit to the city since yesterday, also said BJP's stand on forced conversions was clear and the government was ready to bring a law to ban them.
"BJP is clear about its stand on compulsory conversions. Parliamentary Affairs Minister Venkaiah Naidu has said in Parliament that the government is ready to bring in a law against compulsory conversions. Are the so called secular parties ready to support it?" he asked.
"There is nothing called indirect alliance in politics. Whatever alliance we have it will be known and come in the press. Even yesterday, our BJP leaders have strongly criticised the Tamil Nadu Government in the public meeting (addressed by him)," Shah said replying to a query.
The BJP chief said he was not criticising the Dravidian parties but the their governments based on performance.
