Senior Congress leader P Chidambaram today said his party is in touch with both Mamata Banerjee's Trinamool Congress and Arvind Keriwal's Aam Aadmi Party to keep the BJP out of power this time in Goa. Refering to the 2017 polls results, when the Congress failed to form the government in Goa despite emerging as the single largest party, he said the party is "doubly guarding" its house and will not let it "be burgled" this time.
