The reason is that the former Uttar Pradesh chief minister Kalyan Singh, who parted ways with the BJP twice in the past, is all set to share the dais with NaMo tomorrow.
81-year-old Kalyan Singh's "pro-hindutva image" and OBC background may help BJP in cashing on LS polls next year.
Kalyan Singh has been invited at the first much-awaited Modi's rally as the chief guest and he is likely to play a major role in Saturday's rally.
Kalyan Singh was the undisputed king of UP in 1990s and was at the helm of afffairs as the chief minister as well as the BJP leader.
Besides, Narendra Modi, the BJP president Rajnath Singh, Kalyan Singh, state president Laxmikant Bajpai will address the rally tomorrow.
The party's state-incharge Amit Shah, leader of opposition in Rajya Sabha Arun Jaitley and other prominent leaders will also be share the stage and showcase the strength of a united BJP and will blow the bugle for the next big polls.
With Kalyan-Modi union in Kanpur tomorrow, it can be said that it may "work wonders" for BJP in the general elections next year, as their show of unity will definitely "slow down the cycle speed" of the ruling-Samajwadi Party, which has already earned the ire of the people of their state for recent communal flare-up in Muzaffarnagar district and adjoining areas.
In past, Kalyan Singh had showered praises for Gujarat's Chief Minister Narendra Modi. In April, he had said, " there are a number of able and experienced leaders in the BJP, but acceptability of Narendra Modi as prime ministerial candidate is highest. Modi is a popular leader of the country, who is voice of the people."
The Kurmi leader also described Modi as a "vikas purush".
Kalyan Singh parted ways BJP twice
He first left BJP in 1999 following differences with the then prime minister Atal Bihari Vajpayee.
In 2004, he joined party again and even won from Bulandshahr LS seat, but again due to differences over distribution of party tickets, he left BJP for the second time, only to reunite in 2013.
Kalyan Singh had formed his own party, the Jan Kranti Party (JKP) in 2010, but merged it with the saffron party, early this year, in the run up to the 2014 Lok Sabha polls.
Modi will address total nine rallies in UP till December.
