While protests against the Central rule swirled in a few southern states and much of northeast, where beef is staple for many, Bachu Marak had proposed a rice beer and beef party in the Garo Hills on his Facebook page to mark the three years of the Narendra Modi government.
Coming just after the Youth Congress members publicly slaughtered a calf in Kerala to protest the cattle trade law, Mr Marak's idea drew scathing criticism from senior BJP leaders.
Referring to the "development for all" slogan of the government, senior BJP leader Nalin Kohli said, "How can the slaughter of an animal be the ground for celebrating 'sabka saath sabka vikas'?" Mr Marak, he said, was "welcome to leave the party", which, he said, was ready to sack him.
Bernard Marak - who, much to his party's discomfiture, promised cheap beef if the BJP came to power -- has now called for a bitchi (rice beer) and beef party in Tura on June 10.
But with the party hoping to capture power in the Congress-ruled state in next year's assembly elections, Mr Marak's exit has forced local leaders to call a hasty meeting to chalk out an election strategy.
The two leaders were seen as pillars of the party's growing strength in Garo hills -- a region Chief Minister Mukul Sangma dominates. The Garo-majority region has 24 of the assembly's 60 seats.
