While addressing a Press Conference on May 15, West Bengal Chief Minister Mamata Banerjee launched an attack on BJP keeping a safe corner for her party against Congress. She said that regional political party is strong and therefore BJP cannot fight, hence, she is supporting Congress in Karnataka however it should not fight against her in Bengal. She said, “Wherever a regional political party is strong there BJP cannot fight. The parties which are strong in a particular region should fight together. I am supporting Congress in Karnataka but it should not fight against me in Bengal.”
