Shah, the BJP's veritable principal strategist, will begin his tour of the state with a public meeting in Balmiki Nagar Lok Sabha constituency, a party stronghold that was given away to the chief minister's JD(U) in 2019 as part of seat-sharing arrangements.

The function, scheduled around noon, would coincide with the 'Mahagathbandhan' rally at Purnea, more than 400 km away, where the septuagenarian CM and his 33-year-old deputy will be joined by smaller allies like the Congress and the Left in display of the state's own version of a "united opposition" which Kumar, in particular, believes is the way forward to take on the mighty BJP in next year's Lok Sabha polls.

Shah will be in the state capital a few hours after the rally in West Champaran district. In Patna, he will be addressing a "Kisan Mazdur Samagam" organised to celebrate birth anniversary of peasant leader and freedom fighter Swami Sahajanand Saraswati.

In Bihar, after a gap of more than four months, the home minister is also scheduled to pay his respects in the evening at Takht Harmandir Patna Sahib, the world-renowned Sikh shrine situated at the place where Guru Gobind Singh was born and had spent his early years.

"The BJP stands on the two pillars of organisational strength and ideological commitment and the Union Home Minister's Bihar visit is a reaffirmation of the same. The Mahagathbandhan, on the other hand, has chosen the communally sensitive Seemanchal area to play its card of Muslim appeasement," alleged Nikhil Anand, state BJP spokesman and OBC Morcha national general secretary.

Mrityunjay Tiwari, spokesman of the RJD, to which the deputy CM belongs and which is also the largest constituent of the "Mahagathbandhan", hit back.

"The Purnea rally will sound the bugle for the battle to drive the BJP out of power. Amit Shah's visit will accomplish little. The Home Minister is likely to attempt communal polarization which is the only hope left for the BJP in 2024 elections", Tiwari alleged.
