A day after Prime Minister Narendra Modi told the CBI that no corrupt person should be spared, Rajya Sabha MP Kapil Sibal on Tuesday claimed that the conviction of the corrupt was higher during the UPA rule and asked who is "protecting" those indulging in graft. Addressing a gathering at the diamond jubilee celebrations of the Central Bureau of Investigation (CBI), Modi on Monday said there is today no dearth of political will to act against corruption and officers should take action against the corrupt, however powerful, without any hesitation.
