Even as both the Houses of Parliament were adjourned on Friday after uproar over government policy to allow foreign direct investment (FDI) in retail sector, firebrand BJP leader Uma Bharti issued an open threat to retail chains like Walmart against making a foray into the country.The BJP has strongly opposed the government move to allow retail giants access to the domestic market saying it would kill the business of small traders and create unemployment in the country.Bharti went a step further and threatened to personally lead an attack and set fire to Walmart shops if it entered India. She said she was ready to go to jail for her act."If Walmart opens any outlet in any shopping mall, I will torch that outlet. I am ready to go to jail for this," Bharti told reporters in Uttar Pradesh capital.
