Senior BJP leader M Venkaiah Naidu has accused Congress of adopting double standards on the issue of illegal mining.
 
"Congress which is in opposition in Karnataka is against illegal mining, while the same party which is in power in Andhra Pradesh is turning a Nelson's eye to illegal mining activities there," he said here yesterday.
 
He also flayed Union home minister P Chidhambharam for his 'saffron terrorism' remark and said that terrorism has no colour.
