Aam Aadmi Party (AAP) leader Kumar Vishwas said on Saturday that a BJP MLA had offered him the Delhi chief minister's post in return for support of 12 AAP legislators. "A BJP MLA who is also an old friend had come to my house after elections. I thought he had come to either congratulate or sympathise as I had lost the (general) election. But he told me that his party wanted me to accept the post of chief minister. He also told me he was meeting me at the behest of the BJP leadership," Vishwas told a news channel.
