Dharmani, former BJP MLA from Ghumarwin, along with his supporters joined the BJP in the presence of former Chief minister P K Dhumal and state party chief Satpal Singh Satti.
Talking to mediapersons on the occasion, Dharmani said he will work for victory of BJP candidates in the upcoming Lok Sabha polls.
Congress government in the state has violated the model code of conduct by making announcements and taking decisions after the election schedule announced, Dhumal said, asking the election commission to take action against the party.
Meanwhile, the BJP today deferred the decision on its candidate from Mandi Lok Sabha seat to take on sitting Congress MP Pratibha Singh, wife of chief Minister Virbhadra Singh.
The Congress also deferred the decision on candidates for four Lok Sabha seats from Himachal Pradesh.
