Veteran Goa Congress leader Luizinho Faleiro today quit his party of 40 years amid signs that he is joining the Trinamool Congress of Mamata Banerjee. Shortly before his resignation from the Congress and as an MLA, he effusively praised the Bengal Chief Minister and called her the only "streetfighter" who can give the BJP a tough fight. Sources said he may go to Kolkata on Wednesday to join the Trinamool.
