"Manmohan Singh has no "moral right" to stay in power and must step down in the interest of the country," Ghaziabad MP Rajnath Singh said here.
BJP spokesman Ravi Shankar Prasad had yesterday also accused the Prime Minister of being a "silent spectator" when former Telecom Minister A Raja flouted his directives for ensuring fairness and transparency in the allocation of the 2G spectrum.
Addressing a public rally here last evening, Singh also slammed Mayawati government for deteriorating law and order situation in Uttar Pradesh.
"To give a clean chit to `criminal` ministers and MLAs is an indication to support them and is a way to pollute politics which badly affects law and order situation in the state," the former BJP president said.
No one is safe in UP and the BSP supremo who claims to a Dalit has failed miserably to safeguard Dalit women, Singh said.
BJP Vice President Kalraj Mishra said that the BJP activists would launch an agitation beginning today till February 21 at the district headquarters to `uproot` UP Chief Minister.
