According to sources, Singh on Wednesday, Jan 30 asked party leaders not to express their views regarding the prime minister candidate of the party for the upcoming Lok Sabha election which is expected to be held in 2014.
Singh's gag order surfaced just days after senior BJP leader Yashwant Sinha and Ram Jethmalani's comment where they have openly supported Modi as the PM candidate of the party.
Earlier Yashwant Sinha was quoted as saying, "Discussion over this has been going on for months. Wherever I go, the common people and party workers say they want Narendra Modi to be chosen as the BJP's prime minister candidate."
"After deliberating on the matter for long, I came to the conclusion that if BJP declares him as the prime minister candidate, it will make a huge difference to our electoral prospects," the former union minister said. However, he had clarified that the party will take the final decision.
Sinha is not alone in open support for Modi. The maverick party leader Ram Jethmalani, who recently got his suspension revoked and who has history of going against the party line, also joined the pro-Modi club for the post.
Meanwhile, several other party leaders and one of the important allies of NDA - Shiv Sena claimed that Sushma Swaraj would be the "best choice" for the PM candidate post.
