Three weeks to go for polling in Delhi on February 5 and the incumbent AAP has opened a new front against the BJP. AAP chief Arvind Kejriwal has alleged that the BJP was adding new voters from across the country to the New Delhi constituency using the party MPs' and ministers' addresses to manipulate the electoral roll. In a letter to the Election Commission, Mr Kejriwal accused BJP leaders of engaging in "backdoor tactics" to tamper with the voter list. Today a delegation led by Mr Kejriwal also petitioned Chief Election Commissioner. The BJP called Mr Kejriwal a liar and said he should explain what's the motive behind the AAP government not tabling the CAG reports.
