Panaji, West Bengal Chief Minister and Trinamool Congress supremo Mamata Banerjee on Tuesday slammed the Congress for not doing enough to combat the ruling BJP, while also claiming that a "relationship" may be blossoming between the two national parties.

"Congress makes tall claims that they will fight alone. They fought alone throughout the country, they fought against us too. You still fight against us every day. At least fight the BJP and then make your claims," Banerjee said at a public rally near here.

"Why did I quit the Congress, which I was a part of. I quit sensing a brewing friendship. You are forming a relationship with the BJP. You are trying to save them," she alleged.
