The party organised on June 7 for the Air Marshal-rank officer has raised the hackles of the top brass in the Defence Ministry and security agencies because of the presence of arms dealers and service officials in a private function, sources said here.
Under rules governing the code of conduct of officials, "No Government servant shall, except with the previous sanction of the Government, receive any complimentary or valedictory address or accept any testimonial or attend any meeting or entertainment held in his honour; or in the honour of any other Government servant."
"The IAF has no knowledge of any such private farewell party," an IAF spokesperson told PTI in response to the query.
The Defence Ministry also keeps issuing advisories to its officials and the Services against officers hobnobbing with arms vendors in order to maintain transparency and probity in defence deals.
Major S S Pandey, an expert on military laws, said, "As per the code of conduct for military officers, any officer attending such parties or farewells has to seek permission from his superiors and also give proper reasons for doing so."
