The Ministry of Defence denied today that Prince Harry killed Afghans while drunk, saying he was entirely sober.
The prince was said by a fellow soldier last week to have bombarded Afghan fighters from his Apache helicopter.
Afghanistan's Hizb-i-Islamia Party leader Gulbuddin Hekmatyar accused the prince of bloodsport.
"The British prince comes to Afghanistan to kill innocent Afghans while he is drunk," he said. "He wants to hunt down mojahedin with his helicopter's rockets, without any shame."
An MoD spokesman said the suggestion the prince was drunk was "simply absurd."
He said: "The consumption of alcohol by UK military personnel is not permitted under any circumstances while deployed in Afghanistan."
The spokesman declined to comment on the prince's bombing activities.
Foreign Minister Alistair Burt's admission that the Cameron government has "supported" a survey of attitudes to US drone strikes in Pakistan's tribal areas amounts to a tacit admission of British involvement.
