With the government facing attack over multiple scams, Prime Minister Manmohan Singh today promised a strong Lokpal to end corruption in high places and asserted that hunger strikes will not help address the problem, in an apparent reference to Anna Hazare's agitation. Addressing the nation for the eighth consecutive year on the occasion of Independence Day, Singh said no government has a "magic wand" to deal with the problem of corruption which needs to be tackled on many fronts and asked all political parties to "stand shoulder to shoulder" in this fight.
