Taking on Congress General Secretary Rahul Gandhi, Uttar Pradesh Chief Minister Mayawati today said he should focus more on Delhi than her state UP."Instead of expressing his anger here, it would be better if the Yuvraj of Congress vents his ire at the Congress-led Central government for its failure to contain inflation and adopting step-motherly treatment towards the development of the state," Mayawati said at a function in Lucknow.
