"The Centre has declined permission due to security reasons," SGPC secretary Harcharan Singh told PTI over the phone.
He, however, said that the Centre had told the SGPC that "if anyone wants to visit Pakistan then the Sikh religious body should give an undertaking that he or she is going on its own risk".
"We are yet to decide on it (whether to send the delegation)," he said.
Another delegation, which was to visit Pakistan last month for the martyrdom day of Guru Arjan Dev, was also denied visas due to alleged lack of clearance from the Centre.
