Aam Aadmi Party's Raghav Chadha launched a blistering attack on the government today during the debate on the Delhi Services bill in parliament, exhorting the BJP to follow their own leaders -- Atal Bihari Vajpayee and LK Advani -- who wanted full-fledged statehood for Delhi. The BJP, he alleged, is reacting to the fact that they have lost multiple consecutive elections in Delhi. In effect, they are violating federalism and are changing the Constitution without having to cross the hurdle of passing a Constitutional amendment bill.
