Vishwa Hindu Parishad Working Chairman Praveen Togadia on Monday demanded that Prime Minister Narendra Modi formulate and promulgate a law to protect cows in the country."If you can make law on Goods and Services Tax at 12 a.m., and the law on Triple Talaq, why can't you make law to protect cows," Togadia said at a VHP meeting here.He warned Modi to be prepared for losing power if he did not ensure a law to protect cows but if the government did make such a law he will take the BJP flag around the country to ensure the party retained power at the Centre.Togadia said that he had not met Modi for the past 12 years and would go to Delhi soon to meet him regarding cow protection, state advisories on vigilantes and the Ram Temple at Ayodhya.The VHP leader said that his organisation and the Rashtriya Swayamsevak Sangh had gheraoed Parliament in 1966 and there was a huge difference between those times and the present. "Now we have our own government at the Centre and a law on cow protection should be made," he added.
