Bahujan Samaj Party (BSP) chief Mayawati on Friday made light of chief ministerial candidate of the Congress in Uttar Pradesh Sheila Dikshit and said she will have no impact in the state."She has allegations of graft of crores of rupees and over that she is an old lady," she said here. She also accused Dikshit of doing nothing for the Dalits in Delhi when she was chief minister.Reacting to the appointment of actor-turned-politician Raj Babbar as the Uttar Pradesh Congress Committee chief, the former chief minister said he was a political grasshopper who had no loyalty or political ideology.The Congress has a huge dearth of leaders and hence it is propping up leaders from other states, she said.
