New Delhi, Sep 26 (UNI) Congress leader Pawan Khera on Saturday stepped up his attack on the Election Commission of India (ECI), describing its latest press note on the Special Intensive Revision (SIR) of electoral rolls as “too lame, too little, too late” and alleging that it had failed to answer key questions arising from recent media reports on changes to Form 6, the functioning of ECINet and the exclusion of voters in Goa.
