Shimla, Sep 9 - A senior leader of the Bharatiya Janata Party (BJP) in Himachal Pradesh Wednesday resigned from party post after the opposition Congress raked up his alleged involvement in a call girl racket.

The Congress had been demanding a Central Bureau of Investigation (CBI) probe into the alleged call girl scandal after chairman of the BJP media advisory committee Rajendra Rana and a senior government functionary were reportedly found with some women in a posh hotel here last week.

'Rana's resignation was accepted this (Wednesday) evening. We are inquiring into the allegations of the Congress. If these are true, nobody would be spared,' Chief Minister Prem Kumar Dhumal told IANS.

No first information report (FIR) has been registered so far in the incident.
